HP 8753ES Option 011 Speciﬁcations and Characteristics

Deﬁnitions

All speciﬁcations and characteristics apply over a 25 °C ±5 °C range (unless otherwise stated) and 1/2 hour after the instrument has been turned on.

Speciﬁcation (spec.): Warranted performance. Speciﬁcations include guardbands to

account for the expected statistical performance distribution, measurement uncertainties, and changes in performance due to environmental conditions.

Characteristic (char.): A performance parameter that the product is expected to meet

before it leaves the factory, but that is not veriﬁed in the ﬁeld and is not covered by the product warranty. A characteristic includes the same guardbands as a speciﬁcation.

Typical (typ.): Expected performance of an average unit which does not include

guardbands. It is not covered by the product warranty.

Nominal (nom.): A general, descriptive term that does not imply a level of performance. It

is not covered by the product warranty.

Calibration: The process of measuring known standards from a calibration kit to

characterize a network analyzer’s systematic (repeatable) errors.

Corrected (residual) Performance: Indicates performance after error correction

(calibration). It is determined by the quality of calibration standards and how well “known” they are, plus system repeatability, stability, and noise.

Uncorrected (raw) Performance: Indicates instrument performance without error

correction. The uncorrected performance affects the stability of a calibration.

Option 011: This includes all options available with Option 011 unless noted otherwise.

HP 8753ES Option 011 Speciﬁcations and Characteristics

Corrected System Performance

The speciﬁcations in this section apply for measurements made using 10 Hz IF bandwidth, no averaging, and at an environmental temperature of 25 ±5 °C, with less than 1°C deviation from the calibration temperature. Assumes that an isolation calibration was performed with an averaging factor of 16.

6. STIMULUS function block. The keys in this block allow you to control the analyzer source's frequency, power, and other stimulus functions.

7. RESPONSE function block. The keys in this block allow you to control the measurement and display functions of the active display channel.

8. ACTIVE CHANNEL keys. The analyzer has two independent primary channels and two auxiliary channels. These keys allow you to select the active channel. Any function you enter applies to the selected channel.

9. The ENTRY block. This block includes the knob, the step keys, the number pad, and the backspace key. These allow you to enter numerical data and control the markers.

You can use the numeric keypad to select digits, decimal points, and a minus sign for numerical entries. You must also select a units terminator to complete value inputs.

The backspace key has two independent functions: it modiﬁes entries, and it turns off the softkey menu so that marker information can be moved off of the grids and into the softkey menu area. For more details, refer to the “Making Measurements” chapter in the user’s guide.

10. INSTRUMENT STATE function block. These keys allow you to control channel-independent system functions such as the following:

• copying, save/recall, and HP-IB controller mode

• limit testing

• external source mode

• tuned receiver mode

• test sequence function

• harmonic measurements (Option 002)

• time domain transform (Option 010) HP-IB STATUS indicators are also included in this block.

12. PROBE POWER connectors. These connector (fused inside the instrument) supply power to an active probe for in-circuit measurements of ac circuits.

13. R, A, and B connectors. These connectors allow you to apply input signals when creating your own test setup. In addition, these connectors allow you to use the HP 85046A/B, HP 85044A/B test sets to simplify measurement setup.

14. RF OUT connector. This connects the RF output signal from the analyzer to a test set or power splitter.

• the instrument uses a mechanical switch, for example Options 85 and 007.

• different channel power ranges (PORT POWER UNCOUPLED) which puts the test set switch in HOLD mode except Option 400 (dual step attenuators).

• the user manually puts the test set switch in HOLD mode (TESTSET SW 0 or >1).

Front/Rear Panel

Rear Panel Features and Connectors

Figure 2-3 illustrates the features and connectors of the rear panel, described below.

Requirements for input signals to the rear panel connectors are provided in the speciﬁcations and characteristics chapter.

1. HP-IB connector. This allows you to connect the analyzer to an external controller, compatible peripherals, and other instruments for an automated system. Refer to Chapter 6 , “Options and Accessories” for HP-IB information, limitations, and conﬁgurations.

2. PARALLEL interface. This connector allows the analyzer to output to a peripheral with a parallel input. Also included, is a general purpose input/output (GPIO) bus that can control eight output bits and read ﬁve input bits through test sequencing. Refer to Chapter 6 , “Options and

Accessories” for information on conﬁguring a peripheral. Also refer to The

GPIO Mode” in “Operating Concepts” of the user’s guide.

3. RS-232 interface. This connector allows the analyzer to output to a peripheral with an RS-232 (serial) input.

4. KEYBOARD input (mini-DIN). This connector allows you to connect an external keyboard. This provides a more convenient means to enter a title for storage ﬁles, as well as substitute for the analyzer's front panel keyboard.

5. Power cord receptacle, with fuse. For information on replacing the fuse, refer to the installation and quick start guide.

6. Line voltage selector switch. For more information, refer to the installation and quick start guide.

7. Fan. This fan provides forced-air cooling for the analyzer.

8. 10 MHZ PRECISION REFERENCE OUTPUT. (Option 1D5)

9. 10 MHZ REFERENCE ADJUST. (Option 1D5)

10. EXTERNAL REFERENCE INPUT connector. This allows for a

frequency reference signal input that can phase lock the analyzer to an external frequency standard for increased frequency accuracy.

The analyzer automatically enables the external frequency reference feature when a signal is connected to this input. When the signal is removed, the analyzer automatically switches back to its internal frequency reference.

11. AUXILIARY INPUT connector. This allows for a dc or ac voltage input from an external signal source, such as a detector or function generator, which you can then measure, using the S-parameter menu. (You can also use this connector as an analog output in service routines, as described in the service guide.)

12. EXTERNAL AM connector. This allows for an external analog signal input that is applied to the ALC circuitry of the analyzer's source. This input analog signal amplitude modulates the RF output signal.

13. EXTERNAL TRIGGER connector. This allows connection of an external negative-going TTL-compatible signal that will trigger a measurement sweep. The trigger can be set to external through softkey functions.

14. TEST SEQUENCE. This outputs a TTL signal that can be programmed in a test sequence to be high or low, or pulse (10 µseconds) high or low at the end of a sweep for robotic part handler interface.

15. LIMIT TEST. This outputs a TTL signal of the limit test results as follows:

• Pass: TTL high

• Fail: TTL low

16. MEASURE RESTART. This allows the connection of an optional foot switch. Using the foot switch will duplicate the key sequence

Meas

17. TEST SET INTERCONNECT. This allows you to connect the analyzer to an HP 85046A/B or 85047A S-parameter test set using the interconnect cable supplied with the test set. The S-parameter test set is then fully controlled by the analyzer.

18. BIAS INPUTS AND FUSES. These connectors bias devices connected to

2-10

port 1 and port 2. The fuses (1 A, 125 V) protect the port 1 and port 2 bias lines.

Where to Look for More Information

Additional information about many of the topics discussed in this chapter is located in the following areas:

• "Making Measurements" in the user’s guide contains step-by-step procedures for making measurements or using particular functions.

• "Printing, Plotting, and Saving Measurement Results" in the user’s guide contains instructions for saving to disk or the analyzer internal memory, and printing and plotting displayed measurements.

• "Optimizing Measurement Results" in the user’s guide describes techniques and functions for achieving the best measurement results.

• “Operating Concepts” chapter of the user’s guide contains explanatory-style information about many applications and analyzer operation.

• The programmer’s guide provides a complete description of all HP-IB mnemonics.

Guide Terms and Conventions

The eight keys along the right side of the analyzer display are called softkeys. Their labels are shown on the display. The softkeys appear in shaded boxes in this chapter (for

example, ). The labeled keys that are on the front panel of the analyzer are called front-panel keys or hardkeys. The front-panel keys appear in unshaded boxes in

this chapter (for example, ).

• modiﬁes entries and test sequences

• moves marker information off of the graticules The backspace key will delete the last entry, or the last

digit entered from the numeric keypad. The backspace key can also be used in two ways for modifying a test sequence:

The second function of this key is to move marker information off of the graticules so that the display traces are clearer. If there are two or more markers activated on

a channel on the right side of the display, pressing will turn off the softkey menu and move the marker

information into the softkey display area. Pressing , or any hardkey which brings up a menu, or a softkey, will restore the softkey menu and move the marker

information back onto the graticules.

Power meter calibration occurs on each sweep. Each measurement point is measured by the power meter, which provides the analyzer with the actual power reading. The analyzer corrects the power level at that point. The number of measurement/correction iterations performed on each point is determined by the

changes the stimulus center value to the stimulus value of the active marker, and centers the new span about that value.

sets the CW frequency of the analyzer to the frequency of the active marker. This feature is useful in automated compression measurements. Test sequences allow the instrument to automatically ﬁnd a maximum or minimum

point on a response trace. The command sets the instrument to the CW frequency of the active marker. When power sweep in engaged, the CW frequency will already be selected.

adjusts the electrical delay to balance the phase of the DUT. This is performed automatically, regardless of the format and the measurement being made. Enough line length is added to or subtracted from the receiver input to compensate for the phase slope at the active marker position. This effectively ﬂattens the phase trace around the active marker, and can be used to measure electrical length or deviation from linear phase. Additional electrical delay adjustments are required on DUTs without constant group delay over the measured frequency span. Since this feature adds phase to a variation in phase versus frequency, it is applicable only for ratioed inputs.

provides a tabular listing on the analyzer display of the key parameters for both channels. The screen menu is presented to allow hard copy listings and access new pages of the table. Four pages of information are supplied. These pages list operating parameters, marker parameters, and system parameters that relate to control of peripheral devices rather than selection of measurement parameters.

displays a polar format. Each point on the polar format corresponds to a particular value of both magnitude and phase. Quantities are read vectorally: the magnitude at any point is determined by its displacement from the center (which has zero value), and the phase by the angle counterclockwise from the positive x-axis. Magnitude is scaled in a linear fashion, with the value of the outer circle usually set to a ratio value of 1. Since there is no frequency axis, frequency information is read from the markers.
