General Information Regarding the CE Marking

All ROHDE & SCHWARZ measuring instruments comply with the regulations of the EMC directive. The ROHDE & SCHWARZ conformity evaluation is based on applicable professional and product standards. In cases where multiple limit values can be used, ROHDE & SCHWARZ will apply the stricter standard of the two. With regard to interference emission, the limit values for businesses and commercial operations including the small business sector are applied (Class 1B). For the susceptibility to interference emissions, the applicable limit values for the industrial sector are used. The signal and data cables that must be connected to the device during operation will necessarily affect the compliance with the acceptance limits to some extent. However, the cables used for this purpose will vary, depending on the application. For operation of the device, the following information and conditions should therefore be observed with regard to interference emission and susceptibility:

1. Data Cables

All connections between measuring instruments or their interfaces and external devices (printers, computers, etc.) must always be implemented with adequately shielded

cables. Unless the user manual species a shorter maximum

cable length, the data cable (input/output, signal/control) may not exceed a total length of 3 m, and may not be located outdoors. If the device interface allows the connection of more than one cable, only one may be connected at a time. Data cables in general should always be double-shielded cable. For the IEEE bus cable, the double-shielded cable HZ72 is recommended and can be ordered from ROHDE & SCHWARZ.

2. Signal Cables

Signal cables used for signal transmission between the measurement point and the measuring device should generally be kept as short as possible. Unless a shorter maximum

cable length is specied, the signal cables (input/output,

signal/control) may not exceed a total length of 1 m, and may not be located outdoors. All signal cables must be shielded (RG58/U coaxial cable). Care must be taken to achieve a proper ground connection. For signal generators, doubleshielded coaxial cables (RG223/U, RG214/U) must always be used.

General Information

3. Impact on the Equipment

In the presence of strong high-frequency electric or

magnetic elds, unwanted signal components may enter

the equipment, despite careful setup of the connected cables and lines. With ROHDE & SCHWARZ measuring instruments, this will neither be destructive nor lead to the shutdown of the equipment. As a result of such external conditions, the displayed values and readings may show minor deviations with respect to the applicable instrument

specications in individual cases.

This instrument is designed in accordance with EN 61010-1 (VDE 0411 Part 1), Safety Requirements for Electrical Equipment for Measurement, Control and Laboratory Use, and left the factory in perfect condition. It thus also meets the requirements of European Standard EN 61010-1 and the international standard IEC 61010-1. To maintain this condition and ensure safe operation, the user

All exposed metal parts have been tested against the AC power leads with a test voltage of 2200 VDC. The instru-

ment complies with overvoltage category CAT II (600V). To

ensure safe operation, the instrument may only be operated from a properly grounded power outlet. Plug in the power cord before connecting any signal circuits. Never use the product if the power cable is damaged. Check the power cable on a regular basis to ensure that it is in proper operating condition. Take appropriate safety measures and carefully lay the power cable to ensure that the cable will not be damaged and that no one can be hurt by, for example, tripping over the cable or suffering an electric shock. Any time there is reason to believe that safe operation is no longer possible, the instrument must be taken out of service and secured against inadvertent use.

Safe operation is not possible:

❙ If the instrument shows visible damage ❙ If the instrument is no longer working ❙ Following long-term storage under unfavorable conditions

(e.g. outdoors or in damp rooms)

❙ After severe transport stress (e.g. in packaging that does

not meet the minimum conditions for shipping by post, rail or truck)

Prior to switching on the product, always ensure that the nominal voltage set on the product matches the nominal voltage of the mains supply. If a different voltage is to be set, the mains fuse of the product may have to be changed accordingly.

1.5 Intended Use

This instrument is only intended to be used by persons who are familiar with the risks associated with measuring electrical quantities. The instrument may only be operated with a properly grounded power outlet. Never use a “cheater plug” or other means to defeat or disconnect the protective ground lead. The power plug must be connected before any signal circuits are connected. The product may be operated only under the operating conditions

and in the positions specied by the manufacturer, without

the product's ventilation being obstructed. If the manufac-

turer's specications are not observed, this can result in electric shock, re and/or serious personal injury or death.

Important Information

1.9 CAT II

This instrument is intended for measurements on circuits that are or are not connected directly to the normal (low-voltage) AC power grid. The device complies with measurement category CAT II; the input voltage must not exceed 600 V

in a CAT II application.

RMS

The following information relates exclusively to user safety. Other aspects, e.g. the maximum permissible

input voltage, are specied in the technical data sheets

and must also be observed. Indirect measurements on the power grid may be performed by means of appropriate transducers (e.g. current probes) that meet or exceed the requirements of the protection class applicable to the measurement task. When measuring, the transducer’s

measurement category – as specied by the manufacturer

– must be observed.

Measurement categories

The measurement categories relate to transients superimposed on the AC line voltage. Transients are short, very fast (steep) voltage and current changes that may occur either periodically or non-periodically. The amplitude of possible transients increases as the distance to the source of the low-voltage network decreases.

The measuring circuit is equipped with a current overow

fuse against excess current that cannot be serviced or replaced by the user.

1.11 Limit Values

The R&S HMC8015 is equipped with an overload protection circuit. The overload protection circuit is used to prevent damage to the unit, and to protect against possible electrical shock. The limit values of the unit must not be

exceeded. The front panel of the R&S HMC8015 species

the protection limit values in order to ensure safe operation of the unit. These protection limits must be strictly observed:

❙ Measurement category IV: Measurements at the

source of the low-voltage network (e.g. on electricity meters).

❙ Measurement category III: Measurements in a building

network (e.g. distribution panels, circuit breakers, permanently installed electrical outlets, stationary motors, etc.).

❙ Measurement category II: Measurements on circuits

directly connected to the low-voltage power grid (e.g. household appliances, power tools, etc.)

❙ 0 (Devices with no measurement category rating): Other

circuits that are not directly connected to the power grid.

1.10 Supply Voltage

Before turning on this device, please check that the available supply voltage (115 V or 230 V ±10 %, 50 Hz to 60 Hz)

matches the specications on the supply voltage selector

switch of the device. If this is not the case, the supply volt-

age must be adjusted using the switch. The mains voltage

selector switch is located on the rear panel of the unit.

The unit has a main power fuse, which is located on the rear panel of the unit for uncooled IEC connectors. Depending on the supply voltage setting, a fuse of the correct type must be installed.

4 Connecting a

Device under Test

4.1 Connecting a Device under Test via Adapter

Fig. 4.1: Connecting HZC815 DE version to ¸HMC8015.

A device under test (DUT) can easily and securely be connected to the ¸HMC8015 using the optional HZC815 socket adapter. In this case, the cables enclosed with the HZC815 (length = 25 cm) are connected to the ¸HMC8015 socket on the front panel. The connection of the socket adapter to the ¸HMC8015 front panel is determined by the color of the HZC815 accessory cables. The cables on the socket adapter represent an extension of contacts for a standard AC outlet with grounded safety sockets and are used for measuring a DUT. Power is supplied to the HZC815 socket adapter through the uncooled IEC plug on the top of the adapter and a power cord.

Fig. 3.2: Manually entering the license key.

There are 3 different types of HZC815 available ex factory:

❙ HZC815-DE: DE version; EU socket adapter (230V) ❙ HZC815-UK: UK version; UK socket adapter (230V) ❙ HZC815-US: US version; US socket adapter (115V)

Fig. 4.2: HZC815 DE, UK and US version plug adapters.

The HZC815 standard AC grounded safety outlet system is only approved for a 10 A continuous load. A load of 20 A would destroy the adapter.

On the sides of the HZC815 adapter, special faceplates hide mounting screws. The socket adapter can be permanently mounted with these mounting screws if so desired.

4.2.1 Internal Jack Wiring

Options/Upgrade Vouchers

Fig. 4.3: HZC815 DE version plug adapter with mounting screws.

4.2 Connecting a Device under Test Directly

The ¸HMC8015 can measure voltages up to 600 V and currents up to 20 A

. In these cases, a device under

RMS

test (DUT) can be directly connected to the power analyzer

using the 4 mm safety jacks on the front panel.

Before the start of each measurement, the signal cables to be used

must be checked for damage and wear.

Voltages are measured using the red V jack; currents are measured using the blue A jack. The black COM jack acts

here as the shared measuring input for voltage and current measurement.

If the maximum values for current and voltage are exceeded, the ¸HMC8015 power analyzer is automatically switched off.

If the safety warning “Overcurrent Protection” appears on the screen, then more than 2 A were supplied in the low current range. The unit switches itself off in order to protect the internal shunt. In this case, switch to the automatic range selection (AUTO) or a higher range (> 500 mA) manually.

Fig. 4.4: Internal wiring of A, V and COM jacks.

The 4 mm A, V and COM safety jacks on the front panel

are not electrically isolated and separate from each other, and therefore offer several methods for measuring a DUT:

❙ Voltage-based measurement ❙ Current-based measurement ❙ Measurements via external shunt / current probe

4.2.2 Voltage-Based Measurement

Fig. 4.5: Voltage-based measurement.

Voltage-based measurement is typically used with high currents, since the voltage drop at the shunt increases as the current increases. The voltage U is correctly measured at the load.

Fig. 4.6: Voltage-based measurement, wiring example.

4.2.3 Current-Based Measurement

Current-based measurement is preferred with low currents

and high voltages, because it prevents current owing through the voltage measuring jack from going through

the shunt, which would falsify the reading. With this measurement type, the current reading must be inverted (IN-

VERT) using the ACQ menu and softkey menu CURRENT. In addition, the I and COM cables need to be reversed (see Fig. 4.8).

4.3 Sensor Menu

The Sensor conguration menu is opened via the EXT

menu and the softkey menu SENSOR. Press softkey ACTIVATE to activate (ON) or deactivate (OFF) the sensor measurement. When the sensor measurement is activated (ON), the automatic current measurement (AUTO) is deactivated (if it was activated previously).

Fig. 4.10: Sensor menu.

Fig. 4.8: Current-based measurement, wiring example.

4.2.4 Measurements with an External Shunt or

Clamp-on Current Probe

The 4 mm safety jacks IN and COM are used for making

measurements with an external shunt or clamp-on current probe. Safety plugs connect the shunt or clamp-on probe

directly to the jacks. Accessories such as HZC50 or HZC51

can be used for the clamp-on probe.

The softkey ACTIVATE activates the sensor inputs IN and COM on the instrument front panel (hardware switch).

Use the softkey RANGE and the rotary control knob to select the maximum measuring range for the measured

voltage. The available settings are 100mV, 1V and 4V. As a rule, the 100mV range is appropriate for measurements on shunts, while 1V and 4V are used for measurements

with a current probe. This setting is referenced to the peak value.

Example for shunt:

Set RESISTANCE to 1Ω. Set RANGE to 4V.

Convert as follows:

1V = 1A 4V divided by CF3 = 1.33A. Use the cell conguration to display this power range as

IRANGE on the screen.

Fig. 4.9: HZC51 Clamp-on current probe.

The connection of a clamp-on probe through a BNC adapter is not allowed, since depending on the polarity of the volt-

age, the measuring voltage may be present across the BNC

plug coupling.

Fig. 4.11: Example of a sensor.

Use softkey MODE and the rotary control knob to select the sensor mode. The available modes are SHUNT (to connect an external shunt) and CLAMP (to connect a current probe, e.g. HZC50 / HZC51). The Sensor menu

changes dynamically to match the selected sensor mode. In sensor mode SHUNT, softkey RESISTANCE is used to enter the value of the externally connected shunt in ohms. Select the value using the rotary control knob or press the SHIFT button to input the value numerically. If you entered the value numerically, press the appropriate unit on the

softkey menu to conrm the value. Once the shunt value

is entered, all measured values (current, power and values derived from these) can be calculated correctly and displayed. Manual calculations are no longer necessary. The data from the external shunt is converted to the correct measured values internally.

5.1 Using the Instrument for the First Time

Pay particular attention to the safety instructions indicated

above when using the instrument for the rst time!

After connecting the uncooled IEC power cable and operating the power switch on the rear panel, the unit can be switched on by pressing the POWER button on the front panel. A help screen appears automatically. If you do not want to see the help screen, it can be hidden with the HIDE function. With the HIDE FOREVER softkey, the help screen feature will be disabled and no longer automatically displayed after restarting. After doing this, the help function can only be opened using the HELP button.

Whenever the power analyzer is switched on, it is in the same mode as when it was last shut down. All device settings are stored in nonvolatile memory (NVM) and retrieved when restarting.

Fig. 4.12: Sensor mode.

In sensor mode CLAMP, softkey RATIO and the rotary con-

trol knob are used to dene a conversion factor. This factor denes how many millivolts the sensor transmits when a current of 1A is applied. Once the factor is entered, all

measured values (current, power and values derived from these) can be calculated correctly and displayed. Manual calculations are no longer necessary. Available factors are

1mV/A, 10mV/A and a user-dened value (USER). The conversion factors 1mV/A and 10mV/A are appropriate for

the current probes HZO50 and HZO51, for example. If you are using a current probe from a different manufacturer, use the rotary control knob to select the factor or use the SHIFT button to input the factor numerically.

5.3 Multifunction Softkeys

The menu eld that appears on the screen can be manipulated using the softkeys on the right side of the screen. After a menu is activated by using the function keys on the front panel, control and conguration of the menu functions is done by using the softkeys. If a device function is

not available within a specic setting (e.g. if an option or

upgrade voucher is not installed), then the corresponding softkey is disabled and the caption is grayed out. Close a menu or jump back one menu level using the softkey at the very bottom. In addition, the Quick Menu and the

softkeys 1 to 4 can be used to congure the display of the

measuring parameter cells. If the softkey of the already

active conguration page is pressed again, it is possible

to toggle between a display of six and 10 parameter cells.

Each cell can be fully customized. Up to four conguration

menus are available.

Measuring Parameter Options (“Cells”)

The individual functions and operating modes of the power meter can be selected using the buttons on the front panel. To select a device function, the corresponding function key is pressed. The white LED inside the key is lit as an indication that the function is active. The editing of a cell is activated by pressing on the rotary control knob

or one of the arrow keys. The rst cell on the top left is

highlighted in blue. The relevant parameter cell can then be selected using the rotary control knob or the arrow keys. Once a parameter cell is selected, the parameter list

can be opened by pressing the rotary control knob again. When a measuring parameter has been selected, it can be

conrmed by pressing the rotary control knob, or after 20

seconds without input, the unit will automatically return to the previous screen (see Section 9.3.5 Key Fallback Time).

5.5 Readout Display

The R&S®HMC8015 power analyzer has a TFT color display. The screen is divided into two sections. The rst section is the status bar, in which the currently active modules and interface information are displayed. Table 3.2 presents a general overview of the power meter’s split screen with all possible function displays and their descriptions.

Fig. 5.4: Readout display with six active cells.

The eld of cells is variable and dependent on the operating mode. In NUMERIC mode (set by default), typical numeric measurement values, such as power, voltage, current etc., are displayed. By contrast, in HARMONICS mode (HVC151 option required), the harmonics of the signals are displayed as bar graphs. Each mode has its own menu

structures, which can be congured by using the softkeys.

By default, the display consists of either six or 10 cells with

four different conguration pages.

Fig. 5.3: Selecting the measurement function.

Fig. 5.5: Readout display with 10 active cells.

With the HOLD function, the current measurement results are paused and shown on the display. Therefore when the HOLD button is pressed (button is lit), the particular measurement values are frozen on the display. The data recording is then running in the background. If the HOLD button is pressed again (LED turned off), the function is deactivated.

Setting Parameters

Using the NULL button, the current readings are taken as reference values and any deviation from them is shown on the display. If the NULL function is activated, the LED inside the button is lit. To deactivate the NULL function, press the button again (LED turned off).

If the device shows only dashes “---” on the display, the ¸HMC8015 could not determine a valid frequency. This can occur, for example, when the AC function was selected and the signal amplitude is too small or when the measuring range has been set too high.

5.6 Selecting the Measuring Range

The individual functions and operating modes of the R&S®HMC8015 unit can be selected using the buttons on the front panel. Basic functions, such as voltage or current measuring range, can be selected through the corresponding function keys. Using the U, I, U and I keys, the measuring range can be increased or decreased manually. U or I switches to the next higher, U or I to the next lower voltage or current measuring range.

In automatic range selection mode, this leads to a switch to the next higher range if the signal readings exceed

120% of the current measuring range. The unit switches to the next lower range if 0.6s have elapsed since the last range change and the RMS reading is within 95% of the

next smaller measuring range.

Moreover, by using the ACQ menu, the automatic measuring range selection (AUTORANGE) for current or voltage can be activated (ON) or deactivated (OFF) in the VOLTAGE or CURRENT softkey menu. The manual range selection is automatically disabled when using AUTORANGE.

In the case of manual range selection, if the applied value is too large, the display will show the message “OL” (overload).

Fig. 5.6: Example of measuring range display.

Push long the U , I , U and I keys to activate the automatic measurement range mode.

Using the URANGE or IRANGE measurement parameters, the modulation of the selected measuring range can be graphically displayed (bar graph) on the screen. If the measuring range is manually adjusted with the U, I, U and I keys, the bar graph is changed accordingly. A red measuring range bar indicates that the measuring range of the incoming signal is too small.

Fig. 5.7: Selecting the measurement function.

If, at crest factor 3, the instrument is in a current measuring range less than 200 mA and automatic current range selection is activated, then the data acquisition hardware automatically switches to the highest current measuring range for any large overcurrent (e.g. 2 A).

❙ Inrush mode:

Triggered display of a signal prole (single shot); INRUSH mode is only available in conjunction with the HOC151

option or the HVC151 upgrade voucher.

6.2.1 Harmonics Mode

Fig. 6.4: Logarithmic readout display in Harmonics mode.

FFT is used to calculate the RMS value and phase angle of

the harmonics. This includes a calculation of the rst 50 harmonics (100kHz max.). Instead of the total RMS value,

the display shows the voltage level or the current level of the individual harmonics selected using the cursor. The cursor, which appears in the form of a small triangle under the indicator bar, is moved using the rotary control knob. The voltage levels (softkey SOURCE U – Quick Menu U) are displayed as blue bars and the current levels (softkey SOURCE I – Quick Menu I) as blue bars. Using SCALING (Quick Menu A or %), it is possible to select a scaling factor for the signal in the Y-axis with reference to the fundamental (ABS or %). The measurement diagram is displayed logarithmically on the screen so that even the smallest signal details are visible.

key NUMBER (Quick Menu #) and the rotary control knob can be used to display the number of harmonics included in the FFT calculation. The softkey SUBSET (Quick Menu E

or O) can be used to dene what harmonics are to be used

in the calculation (EVEN, ODD or all). The voltage U or current I or both can be selected as the source for the FFT calculation (softkey SOURCE).

The FFT is calculated continuously. Settings made using softkeys affect only the display of values on the screen.

Pressing the bottommost softkey closes the HARMONICS menu and opens a Quick Menu while the mode remains active. This permits convenient control of the harmonics settings via the Quick Menu. Pressing the VIEW button and then selecting display mode NUMERIC closes Harmonics mode and returns to the default display mode.

6.2.2 Waveform Mode

The WAVEFORM display mode can be used to display the voltage, current and power simultaneously as a trace on the screen (hardware-based triggering). Exactly one signal period is displayed in the measurement diagram and

automatically scaled to the measuring range nal value.

Softkeys U, I and P are used to display or hide the traces for voltage (blue), current (red) and power (green). In addition, softkey R (Readouts) can be used to display statistical values, including U

Acquisition of the trend is restarted any time the measurement function is changed. The trace scaling is set automatically on the screen and cannot be changed. The softkey TIME BASE can be used to select the temporal

resolution per scale division. The available values are 1s/ Div, 10s/Div, 1m/Div or 10m/Div. The existing trace data

is deleted any time the temporal resolution is changed. The softkey CLEAR deletes the trace data from the screen and starts a new acquisition. VISIBLE is used to activate Source 1 and Source 2 (yellow) or to deactivate them (white).

Pressing the bottommost softkey closes the TRENDCHART menu and opens a Quick Menu while the mode remains active. This permits convenient control of the settings via the Quick Menu. Pressing the VIEW button and then selecting display mode NUMERIC closes Trendchart mode and returns to the default display mode.

6.2.4 Inrush Mode

INRUSH display mode uses an internal hardware buffer to trigger acquisition of a rare event and to output it to the display (similar to the single shot function found on oscilloscopes). This might be used to acquire inrush currents

on loads, for example. After an event occurs, the current and voltage trends are acquired. The trend display starts at the right-hand side of the screen. The softkeys VOLTAGE (Quick Menu U) and CURRENT (Quick Menu I) are used to activate (ON) and deactivate (OFF) the voltage and current traces, respectively. Under SETTINGS, the trigger is set to one of these two values, or it can be selected manually. A threshold (softkey LEVEL) can also be set, as well as the offset between the rising and falling edges (softkey SLOPE). At the full sampling rate, the acquisition runs for

16ms (softkey ACQ. TIME). The sampling rate can also be

varied to permit acquisition of signal sequences of over a minute (see Table 6.3).

The trace display does not update dynamically. Instead, it must be updated manually by pressing softkey ACTIVATE (ON) (Quick Menu A). The trace is updated each time the button is pressed (single shot). The Inrush display cannot be zoomed. A maximum of 8000 measurement values each for current and voltage can be acquired.

Pressing the bottommost softkey closes the INRUSH menu and opens a Quick Menu while the mode remains active. This permits convenient control of the settings via the Quick Menu. Pressing the VIEW button and then selecting display mode NUMERIC closes Inrush mode and returns to the default display mode.

Instrument Functions

6.3 Crest Factor

The crest factor (also known as peak factor) describes the factor by which a signal’s amplitude (peak value) is greater than the rms-calculated effective value. This is important for the measurement of pulse-shaped sizes. For pure si-

nusoidal wave types, the following ratio applies: √2=1.414.

The accuracy of the calculated effective value remains the same as long as the peak value stays within the peak range. A crest factor of 1.8 or higher indicates a strong distortion from the waveform. To evaluate the waveform distortion of non-linear electric loads, the Waveform or TRENDCHART mode can be used.

Example:

If a battery is charged with 4AH and discharged with 3AH, the display will show AHP = 4, AH– = –3 and the

total AH = 1 (i.e. 4 + (–3) = 1).

The Integrator menu can be opened by pressing the softkey INTEGRATOR in the MEAS menu. The relevant integrator mode is then selected using the softkey MODE and the rotary control knob.

6.4.1 Manual Integrator Mode (Default)

Fig. 6.9: Sample conguration for crest factor 6.

From the ACQ menu, the crest factor can be varied between 3 and 6 by using the softkey CREST FACT in the VOLTAGE or the CURRENT softkey menu. When changing the crest factor, the measuring range is adjusted automatically. A crest factor of 5 or higher is used e.g. for sinusoidal waveforms with spikes (see example in Fig. 6.4) and is also required for standby measurements according to IEC

62018.

6.4 Energy Counter (Integrator Values)

The power analyzer makes it possible to display integrator values (WHP, WHM, AHP, AHM) on the screen. These values are also activated via the measuring parameter cell. In this way, the energy use of electronic devices under test (DUT) can be recorded where power consumption is not constant. WHP / AHP represent the power / current in the positive direction and WHM / AHM in the negative direction. WH / AH correspond to the sum of the watt-hour/ ampere-hour positive and negative portions, respectively.

Fig. 6.11: MANUAL integrator menu.

The manual integrator mode is pre-selected by default. Using the START softkey, or directly using the START/ STOP button on the front panel of the instrument, the energy counter can be started as soon as it has been activated (ON) using the ACTIVATE softkey. Pressing either the softkey START or the START/STOP button on the front panel once more will stop the energy counter. The RESET softkey or the RESET button on the front panel will reset the integrator values.

6.4.2 Span Integrator Mode

A start time (START TIME) and an integration time span (DURATION) can be set using the SPAN integrator mode. Once the energy counter has been activated (ON) via the ACTIVATE softkey, the counter will automatically start at the preset start time and then automatically stop after the integration time span (DURATION) has elapsed. The time span for the integration can be set using the rotary control knob or, by using the SET TO CURR. softkey, the current

system time can be applied and adjusted accordingly.

Fig. 6.10: Readout display with integrator output values. Fig. 6.12: Span integration mode selection menu.

Instrument Functions

Initiating the start separately by using the START/STOP button on the front panel is not required. The RESET button on the front panel will reset the integrator values.

The maximum duration for running the energy counter is 96 hours (DURATION).

Fig. 6.13: Setting the integration duration.

Fig. 6.14: Inversion.

blue A jack. In order to record and display the current correctly with this type of wiring, the current direction must be inverted in the ACQ menu using the CURRENT softkey menu and the INVERT softkey. When the INVERT function is activated, it is displayed as a green box around the measuring range displayed in the status bar.

6.4.3 Duration Integrator Mode

The DURATION integrator mode denes how long the

energy counter is active. Using the START softkey, or directly using the START/STOP button on the front panel of the instrument, the energy counter can be started as soon as it has been activated (ON) using the ACTIVATE softkey. After the integration time (DURATION) has elapsed, the energy counter is automatically stopped. The time display in the status bar is replaced with the integration time. The time span for the integration can be set using the rotary control knob or, by using the SET TO CURR. softkey, the current system time can be applied and adjusted accordingly. If the integration time is expired, a new integrator measurement can only be started via START button, if the integrator values were reset with RESET softkey.

6.4.4 External Integrator Mode

(only with the HOC152 option/HVC152 voucher)

Using the external integrator mode (EXTERN), the energy counter can be started and stopped by an external pulse at the digital inputs on the rear panel. Once activated (ON) using the ACTIVATE softkey, the energy counter is automatically started by a “high” signal and automatically stopped by a “low” signal. Initiating the start / stop separately by using the START/STOP button on the front panel is not required.

6.5 Invert Function

The power analyzer also records the sign of the measured current with AC, for the correct calculation of the exact input or output of power and energy, for example. Depending on the external wiring (e.g. with the HZC815 adapter) the voltage or the current is measured inverted. For current-based measurements, the wires going to the

jacks A and COM on the front panel must be swapped

(see Section 4.2.3). When using the HZC815 measuring adapter, the blue cable must therefore be inserted into the

black COM jack, and the black cable is inserted into the

6.6 Acquisition Mode

Fig. 6.15: Selecting the data acquisition mode.

The acquisition of current and voltage is performed simultaneously and so can be compared with a two-channel oscilloscope (16 bit). The sampling frequency is 500 ksample/s. The values displayed on the screen are updated 10 times per second. In the ACQ menu, the data acquisition mode can be selected by using the MODE softkey menu, followed by the MODE softkey. The following settings can be selected:

❙ AUTO: Automatic selection of the data acquisition mode

(default); automatic detection of an incoming signal.

❙ DC: For measuring pure DC loads; in contrast to the AC

mode, there is no synchronization with the signal period, instead synchronization is over a certain period of time (error is displayed if AC signal is applied).

❙ AC: Average value of a voltage / current period

(synchronization with the signal period).

❙ EXTERN: Specifying a signal period via the external BNC

connector DIGITAL IN (only available in conjunction with

option HOC152 / upgrade voucher HVC152); e.g. used

with a fuzzy signal which must be ltered externally.

Instrument Functions

6.6.1 Frequency Filter

The power analyzer R&S®HMC8015 features the following lter settings which can be adjusted in the ACQ menu using the softkey menu MODE (for AUTO and AC only):

❙ Frequencylter:

Reliable acquisition of the zero crossings for the precise determination of the signal period.

❙ Digitallter:

Automatic, adaptive averaging of the lter setting for

several periods to increase accuracy; ideal for highly

uctuating values (values become more stable).

❙ BWL:

Classic low-pass lter (1 kHz) as bandwidth limit (BWL), in order to produce a clean, HF-adjusted signal.

Fig. 6.16: Filters arranged as a chain.

6.6.2 Frequency Source

Use the phase locked loop source frequency synchronization (PLL SRC) softkey to set the reference variable for the fundamental frequency (VOLTAGE/CURRENT). The fundamental frequency of each period is the reference for the measured harmonics of the reading. Voltage (VOLTAGE) is selected as the reference variable by default. The CURRENT setting makes sense for signals with a very small or an irregular current trace. Using the EXTERN function, the frequency can be set via the digital input located on the rear panel (only available in conjunction with the HOC152 option or the HVC152 upgrade voucher).

measuring range modulation, a bar is used to display the limit values. This two-part bar indicates the modulation of

the limit from –100% (minimum modulation) to +100%

(maximum modulation). It is also possible to link the limit function with the ANALOG OUT or DIGITAL OUT (EXT menu). See Section 6.9.

6.7 Peak Hold

The PEAK HOLD displays maximum peak values, ensuring a stable readout display for loads. The sampling frequency is 500 ksample/s. The PEAK HOLD function is activated (ON) or deactivated (OFF) in the ACQ menu by selecting softkey menu PEAK HOLD and softkey ACTIVATE.

If “OL” (Overload) appears on the display, the peak values must be reset on the display using softkey RESET

6.8 Limits

In the MEAS menu, the softkey menu LIMIT can be used

to dene up to six limit values. Once up to six limit values (LIM1 to LIM6) are selected in the cell conguration,

they can be activated (ON) or deactivated (OFF) using the softkey ACTIVATE. The softkey SOURCE and the rotary control knob can be used to select the measurement function for the source. Table 6.4 shows the possible measurement functions. The softkeys HIGH and LOW are used to

If the measuring instrument displays only dashes “-----” on the display, either the limit function is not activated or an error oc-

curred (e.g. limit value LOW ≥ limit value HIGH).

6.9 Analog / Digital Inputs and Outputs

On the R&S®HMC8015 rear panel, there are four BNC connectors that can be used as analog or digital inputs and outputs (Digital / Analog IN/OUT). The connectors are available for limit values and Pass/Fail sorting, for example.

Fig. 6.18: BNC connectors Digital / Analog IN/OUT.

Instrument Functions

6.9.1 Analog IN

The ANALOG IN can be activated (ON) or deactivated (OFF) in the EXT menu by selecting softkey menu ANALOG IN and softkey ACTIVATE. In addition, the AIN

function in the cell conguration can be used to display

the measured value of the analog input signal on the screen.

Fig. 6.19: ANALOG OUT menu.

6.9.2 Analog OUT

The ANALOG OUT can be activated (ON) or deactivated (OFF) in the EXT menu by selecting softkey menu ANALOG OUT and softkey ACTIVATE. The external mode is selected by using softkey MODE and the rotary control knob. The following modes can be selected:

❙ Voltage:

Minimum modulation at the output corresponds to 0V

and maximum modulation corresponds to the measuring range.

❙ Current:

Minimum modulation at the output corresponds to 0V

and maximum modulation corresponds to the measuring range.

❙ Power:

Minimum modulation at the output corresponds to 0W

and maximum modulation corresponds to the maximum current and voltage measuring ranges.

❙ Limit:

The limit module is connected to the analog output. The output modulation is represented as a percentage %.

–100% corresponds to minimum modulation at the output (≙ –5V) and +100% corresponds to maximum modulation (≙ +5V). The limit value (LIM1 to LIM6) is

selected using softkey LIMIT NO and the rotary control knob.

❙ Frequency:

The power analyzer measures the frequency at the DIGITAL IN.

❙ PWM:

The power analyzer measures the relationship between High and Low.

❙ State:

The power analyzer measures the High and Low levels.

The softkey INVERT is used to invert the signal applied at DIGITAL IN. This makes sense in STATE mode, for example.

6.9.4 Digital OUT

The DIGITAL OUT can be activated (ON) or deactivated (OFF) in the EXT menu by selecting softkey menu DIGITAL OUT and softkey ACTIVATE. The external mode is selected by using softkey MODE and the rotary control knob. The following modes can be selected:

❙ Limit:

The limit module is connected to the digital output. The High level at the output corresponds to logical True and the Low level corresponds to False.

function should start. Using the DURATION softkey menu,

the recording duration for the readings is dened.

The maximum logging duration is 96 hours (DURATION).

Using the MEAS button and the LOGGING softkey menu, the data acquisition can be started and various settings can be selected. Using the ACTIVATE softkey, data acquisition and storage can be activated (ON) or deactivated (OFF). Using the STORAGE softkey menu, the type of stor-

age device can be selected (Internal / USB ash drive), as well as the le name (File Name) and the le format (CSV

/ TXT). Using the LOG PAGE softkey, the active measuring parameter cells menu (Quick Menu 1 to 4 on the main screen) can be selected. If LOG PAGE 1 is selected, only

the readings from the rst measuring parameter cell menu

(Quick Menu 1 on the main screen) are recorded. If LOG PAGE 2 is selected, only the readings from the second measuring parameter cell menu (Quick Menu 2 on the main screen) are recorded, and so on.

Using the INTERVAL softkey and the rotary control knob, a measuring interval can be set. The measuring interval is the time between readings. If, for example, the INTERVAL function is set to 5, then a reading is taken every 5 s. The MODE softkey menu offers various logging modes. Select

the UNLIMITED function if you intend to make an innitely

long data record. The limiting factor here is the size of the internal memory (512 kbyte max.) or that of the connected

USB ash drive (4 Gbyte max., FAT/FAT32 formatting). If

the COUNT function is active, the number of recorded events can be set with the COUNT softkey and the rotary control knob. If, for example, an interval of 5 s and a count of 5 are set, then 5 readings will be recorded at intervals of 5 s. If the DURATION function is activated, the recording duration for the readings can be adjusted with the DURATION softkey and the rotary control knob. If the SPAN

function is activated, a logging time span can be dened. Use the softkey menu START to dene when the logging

External USB hard drives (or USB extensions) are not supported. Only USB ash drives with FAT/FAT32 formatting (4Gbyte max.)

are recognized by the R&S®HMC8015.

Using the SPAN function, a start time (START TIME) and a logging time span (DURATION) can be set. Once the logging function has been activated (ON) via the ACTIVATE softkey, the data acquisition will automatically start at the preset start time and then automatically stop after the logging time span (DURATION) has elapsed. The time span for the logging can be set using the rotary control knob or, by using the SET TO CURR. TIME softkey, the current

system time can be applied and adjusted accordingly.

The log function is active if the color of the LOG display in the

status bar has changed to green, or inactive if it is white.

Using the CSV softkey menu, the structure of the CSV le can be congured. This is used to dene the decimal separa-

tor (DEC.SEP.) as well as the line separator (FIELD DELIM.).

Data saved in a CSV le can be opened with Microsoft

Excel, for example, and displayed as graphical charts (see example in Fig. 7.1).

Gaps in the logging may occur under the following circumstances:

8.2 Screenshots

The most important method of storing data for documentation purposes is the screenshot. A screenshot is an

image le that shows the current screen contents at the moment it is captured to a le. However, screenshots can only be saved to a USB ash drive. When a USB ash drive

is connected, directories can also be changed, created or

deleted. The choice of the target directory is conrmed

with ACCEPT.

The R&S®HMC8015 power analyzer allows the user to save all screen displays and user settings. Internal memory is used to store device settings. This type of data can also

be saved to any USB ash drive connected to the unit.

However, screen captures can only be saved to a USB

ash drive. The main menu for the saving and recalling/

uploading of functions is opened by pressing the SAVE/ RECALL button.

8.1 Device Settings

Using the DEVICE SETTINGS softkey menu, the currently active device settings can be saved, and previously saved settings can be retrieved/uploaded.

Pressing the SAVE softkey will open the Save to Memory menu. Using the STORAGE softkey, a possible location (INTERNAL or FRONT) is selected for the device settings to be stored. After selecting the desired storage location and pressing the ACCEPT softkey, the File System Man-

ager is opened. The le name (FILE NAME) can be adjusted to the currently active setting or changed entirely

(the default name is SET). Use the COMMENT softkey to add a comment that will appear in the footer of the File

Manager if the le has been selected. Device settings are

stored in HDS format (binary). The format cannot be changed. The settings are saved using the SAVE command.

The name of the le (FILE NAME) can be adjusted to the currently active setting or changed entirely (the default name is SCR).

The selected le format for the graphic le then determines the color depth and the type of compression. There is no difference in the quality of these formats with respect

to the instrument graphics. The following le formats can

be selected from the softkey menu FORMAT:

❙ BMP = Windows Bitmap Format ❙ PNG = Portable Network Graphic

Using the COLOR MODE softkey and the rotary control knob, the user can choose between GRAYS CALE and COLOR. In GR AYSC ALE, the colors are converted to grayscale, while saving in COLOR saves the image as displayed on the screen. Pressing the softkey SAVE triggers an immediate saving of the current screen to the preset location and using the preset name and format.

A screenshot will be saved (depending on the menu setting) on

a connected USB ash drive by holding down the SAVE/RECALL

button.

Device settings from an old rmware version cannot be loaded with a new rmware version.

To upload les containing saved settings, the LOAD softkey menu is opened by pressing the corresponding softkey. This will open the File Manager, in which the desired

le can be selected using the rotary control knob. Once the storage location and the settings le are selected, the le is uploaded by pressing the LOAD softkey. To remove settings les that are no longer needed, the corresponding le is selected with the rotary control knob and removed

using the REMOVE FILE softkey. When a USB ash drive is connected, directories can be changed or deleted as well.

The menu item DEFAULT SET TINGS provides the ability to upload and return to the factory default settings.

10.1 USB VCP

The available USB VCP drivers have been fully tested and are

available for Windows XP™, VISTA™, Windows 7™, Windows 8™

and Windows 10™ (32 bit and 64 bit).

When using the classic Virtual COM Port (VCP) variant, the user can, after installing the corresponding Windows driver for a terminal program, communicate with the R&S®HMC unit using SCPI commands. The latest USB VCP driver can be downloaded free of charge from the ROHDE&SCHWARZ website <www.rohde-schwarz. com> in the downloads section, and decompressed into an appropriate directory.

tions in the driver le.

In addition, the free HMExplorer software can be used. This Windows application offers the ability to create screenshots for the R&S®HMC8015 in addition to having a terminal program function.

10.2 USB TMC

The modern alternative to a Virtual COM Port (VCP) for external control is using the USB TMC procedure. TMC stands for “Test & Measurement Class” which means that once Virtual Instrument Software Architecture (VISA) drivers have been installed, the connected device can be detected without specialized Windows drivers, and used directly in the corresponding environments. The structure of the TMC procedure is modeled on the GPIB interface. Therefore, the great advantage of the USB TMC is that, by querying special registers, it can be determined whether commands were correctly processed and have been completed. By contrast, when communicating using VCP, testing and polling mechanisms in the control software are needed for this purpose, which may lead to a considerable workload on the device interface. This problem is solved when using the USB TMC by using the TMC status registers, similar to a GPIB interface hardware-based solution through corresponding control lines.

Communications via USB TMC are not supported by the HMExplorer software.

10.2.1 USBTMCConguration

The R&S®HMC8015 power analyzer assumes a generic USB device driver when it is operated in USB TMC mode. The USB Test & Measurement Class (USB TMC) is a protocol that enables GPIB-like communications using USB interfaces and represents a unique device class within the

USB specication. The USB TMC protocol supports service queries, triggers and other GPIB-specic instructions.

The driver is included in the NI Virtual Instrument Software Architecture (VISA) package and can be downloaded from <http://www.ni.com/downloads/ni-drivers/>.

Fig. 10.2: USB VCP settings.

First, the NI-VISA driver must be installed on your Windows system. To do this, download the latest version of the NI-VISA driver package. Decompress the driver

package you just downloaded and follow the installation

instructions.

Here is an example for NI-VISA version 5.4.1:

Open the Windows Device Manager. The device is now listed under “USB Test and Measurement Devices > USB Test and Measurement Device (IVI)”.

10.3.1 Internet Protocol (IP) Networks

In order for two or more network elements to communicate with each other through a network (e.g. measuring instruments, hosts/PCs, etc.), a number of basic connections must be observed, to facilitate the correct and undisturbed execution of the data transmission in networks. Each network element within a network must be assigned an IP address in order for them to exchange data. IP addresses are represented (in the IP version 4 or IPv4) in the form of four decimal numbers separated by periods (e.g.

192.168.15.1). Each decimal number represents a binary number of 8 bits (or one byte). IP addresses are divided into public and private address ranges. Public IP addresses are routed through the Internet and are provided by an Internet Service Provider (ISP). Network elements which have a public IP address can be reached via the Internet as well as exchange data over the Internet directly. Private IP addresses are not routed through the Internet and are reserved for private networks. Network elements which have a private IP address cannot be reached via the Internet and cannot exchange data over the Internet directly.

In order for network elements with private IP addresses to exchange data over the Internet, a router that performs IP network address translation (NAT) must connect them to the Internet. Using this router, which has a private IP address (the LAN IP address) and a public IP address (the WAN IP address), the network elements are connected to the Internet and can exchange data. In cases where network elements only ever exchange data through a local area network (without connection to the Internet), it is best to use private IP addresses. Choose a private IP address for the device and also a private IP address for the host (PC) used to control the device. If you later connect your private network through a router to the Internet, you can keep the previously used private IP addresses for use on your local network.

Fig. 10.10: Display in the device manager.

10.3 Ethernet

For direct connection to a host (PC) or indirect connection using a switch, a double-shielded network cable (e.g. CAT.5, CAT.5e, CAT.5+, CAT.6 or CAT.7) is required, with RJ-45 connectors on both ends. Either a straight or a crossover cable may be used for the network cable.

As with any IP address range, the rst IP address denotes

the network and the last IP address is used as a broadcast IP address, therefore these two IP addresses must be subtracted from the “number of possible host addresses” (see Table 10.1: Private IP address ranges).

In addition to the classication of IP addresses into public

and private address ranges, IP addresses are further divided into classes (Class: A, B, C, D, E). The private IP address ranges described above would fall within categories

A, B, and C. The classication of IP addresses is important

for the allocation of public IP address ranges, and depends mainly on the size of a local area network (i.e. maximum number of hosts on the network), when it is connecting to the Internet (see Table 10.2: Classes of IP addresses).

IP addresses can be allocated as permanent (static) or variable (dynamic). If permanent IP addresses are assigned in a network, an IP address must be set manually for each network element. If variable IP addresses are automatically (dynamically) assigned to the connected network elements, the task of allocating the IP addresses then requires

Remote Operation

a Dynamic Host Conguration Protocol (DHCP) server.

When using a DHCP server, a range of IP addresses can be preset for the automatic allocation of the IP addresses. DHCP servers are typically already integrated into routers. If however a network element (device) is directly connected via a network cable to a host (PC), no IP addresses can be allocated automatically to the measuring device and the host (PC), because in this case, there is no available network with a DHCP server. They must therefore be

specied manually on the device and the host (PC).

With the help of subnet masks, IP addresses are broken up into the network portion and the host portion, simi-

lar to a phone number being broken up into area prex

(international country code and local area code) and phone number (subscriber number). Subnet masks have the same form as IP addresses. They are represented in the form of four decimal numbers separated by periods (e.g.

255.255.255.0). As with the IP addresses, each decimal number represents a binary number of 8 bits (or one byte). The subnet mask manages the separation of an IP address into the network portion and the host portion (e.g. the IP address 192.168.10.10 is split up by the subnet mask

255.255.255.0 into a network part 192.168.10.0 and a host part 0.0.0.10). The allocation is achieved by the conversion of both IP address and subnet mask into binary form, followed by a bitwise logical AND operation between IP address and subnet mask. The result is the network portion of the IP address.

elements (e.g. measuring devices, hosts/PCs etc.) can be simultaneously operated in such a network when using this subnet mask.

Very often, a network will have a default gateway. In most local networks, this gateway is identical to the router used for the Internet (DSL router, ISDN router etc). Using this (gateway) router, a connection can be made to another network. This makes it possible to reach network elements which are not in the same (local area) network, or network elements from the local network can exchange data with network elements from other networks. In order to enable network-wide data exchange, the IP address of the default gateway must also be set. In local networks, the rst IP address within a network is generally used for this (gateway) router. Routers which are used as a gateway in a local area network often have an IP address with a “1” as the last digit of the IP address (e.g. 192.168.10.1).

10.3.2 Ethernet Settings

PC and device must be in the same network, otherwise a connection is not possible.

The network interface card comes with a USB inter-

face and an Ethernet interface. The conguration of

the required parameters is managed directly by the R&S®HMC8015 after “Ethernet” has been selected as the interface, and the PARAMETER softkey has been pressed.

By contrast, the host portion of the IP address is formed by a bitwise logical NAND operation between IP address and subnet mask. By using subnet masks to achieve a variable (dynamic) allocation of IP addresses into network portion and host portion, the user can specify IP address ranges for large as well as small networks individually. This allows the user to operate both large and small IP networks and, if necessary, connect them through a router to the Internet. In smaller local area networks, the subnet mask of

255.255.255.0 is generally used. In this case, the network

portion (the rst three of the four decimal numbers) and the host part (the last decimal number) can be identied

without much mathematical effort, and up to 254 network

Remote Operation

A complete parameter conguration may be performed, including the allocation of a xed IP address. Alternatively,

a dynamic assignment of IP addresses is possible through activation of the DHCP function. Contact your IT manager for more information regarding the correct settings.

Once the device has an IP address, it can be reached with a web browser using this IP, since the Ethernet interface has an embedded web server. When the IP address is entered in the browser address bar (http://xxx.xxx.xxx.xxx), a window will appear with details on the device type and serial number.

If DHCP is used and the R&S®HMC8015 cannot obtain an IP address (e.g. if no Ethernet cable is plugged in or the network does not support DHCP), it takes up to three minutes for a “time out” message to be returned, thereby clearing the interface for

another conguration.

10.3.3 LXI

LAN eXtensions for Instrumentation (LAN LXI) is a device platform for measuring instruments and test equipment that is based on standard Ethernet technology. LXI as a LAN-based successor to GPIB is intended to combine the advantages of Ethernet with the simplicity and ease of use of GPIB.

The R&S®HMC8015 is LXI certied and complies with

Version 1.4 (LXI Core 2011). Advanced features are not supported. The LXI certication central components are the Interchangeable Virtual Instrument (IVI) device drivers. These IVI.net drivers are based on Microsoft’s .NET Framework

4. LabView and LabWindows/CVI drivers that were created based on LabWindows/CVI 2012 are also available.

10.4 IEEE 488.2 / GPIB

In addition to the GPIB features already made available by USB TMC, the R&S®HMC8015 is also available with an option that includes a GPIB interface (R&S®HMC8015-G). This solution may be attractive for those customers who already have an existing GPIB environment. In this way, a new R&S®HMC8015 model can replace any existing outdated equipment with minimal conversion effort. The

conguration of the required parameters is managed by

the R&S®HMC8015 once “IEEE488” has been selected as the interface, and the PARAMETER softkey has been pressed.

The optional IEEE 488 (GPIB) interface can only be installed at

the factory, since the unit must be opened and the warranty seal would have to be broken.
