1. INTRODUCTION

The HI-4455 is a battery-operated broadband Isotropic Electric Field Probe designed for use in making RF exposure measurements in the vicinity of broadcast facilities and industrial RF sources. Applications include: Health and Safety monitoring, measuring microwave transmitters and antennas, EMI monitoring, and measuring the fields generated by ISM equipment. This probe uses optical isolation to minimize field perturbation during measurements.

The HI-4455 probe assembly consists of a conical casing, containing the sensor, which is mounted on one end of a shaft; the other end of the shaft is attached to an extrusion that houses the electronics (Figure 1). The sensor and electronics housing operate-and are calibrated-as a unit.

The HI-4455 measures the field strength in each of three axes. It performs a vector addition calculation on the readings and sends the resultant to the receiver via a fiber optic cable. Frequency response of the HI-4455 is 200 kHz to 40 GHz; dynamic range is 2 to 300 Volts per meter (V/m).

2. GETTING STARTED

UNPACKING AND ACCEPTANCE

Step 1. Upon delivery of your order, inspect the shipping container(s) for evidence of damage. Record any damage on the delivery receipt before signing. In case of concealed damage or loss, retain the packing materials for inspection by the carrier.

Step 2. Remove the probe from its shipping containers. Save the boxes and any protective packing materials for future use.

Step 3. Check all materials against the packing list to verify that the equipment received matches what was ordered. If you find any discrepancies, note them and call ETS-Lindgren Customer Service (+1.512.531.6400) for further instructions.

Be sure that you are satisfied with the contents of your order and the condition of your equipment before installing the probe.

PROBE

A switch, two fiber optic connectors and a battery charger connector are mounted on the HI-4455 electronics housing (Figure 2).

XMIT/RCV

The fiber optic cable assembly from the receiver is attached to the probe via two connectors. The cables are color-coded: white for XMIT, yellow for RCV. Identically colored dots are located on the electronics housing adjacent to these connectors. Be sure that each cable is attached to the proper probe connector.

11

HI-4455 Isotropic Electric Field Probe

Archived 4/2/10

Figure 2: Switch and Connectors

When the fiber optic cables are not attached, always cover the probe connectors with the protective plastic covers supplied with the unit, or with similar material. This prevents dirt or other contaminants from entering the connector and causing communication problems.

ARM/OFF

The ARM/OFF switch activates and deactivates the probe. In the ARM position, the probe is powered by its internal 3.6 VDC NiCd battery: in the OFF position, the probe is inactive. To prolong battery life, set the ARM/OFF switch to OFF at the end of a test sequence or when the probe is not in use.

Charger

A standard fast charger is supplied with the HI-4455. When charging is complete, the fast charger acts as a trickle charger. The battery can be left on this maintenance mode indefinitely and its performance will not degrade.

Battery

The NiCd battery provides up to 17 hours of probe operation when fully charged.

BATTERY CHARGING Introduction

Each HI-4455 probe contains a rechargeable nickel-cadmium (NiCd) battery. A fully-charged battery (nominal output voltage of 3.6 VDC) provides up to 17 hours of continuous operation.

NOTE: ETS-Lindgren charges the internal NiCd battery of the HI-4455 at the factory in order to calibrate the probe prior to shipment. While every effort is made to ensure that your probe arrives ready to use, we cannot guarantee that this will be the case. Always check the condition of the battery prior to making any measurements. To check probe battery voltage, refer to the operation of the Field Monitor or ProbeView software User's Manual.

Charging Procedure

Step 1. Plug the charger into a suitable AC source. Step 2. Set the probe switch to OFF. Insert the plug on the charger

cable into the probe's CHARGER jack. Step 3. The battery is now charging. This may take approximately 1

hour, depending on how deeply the batteries are discharged. When charging is complete, the charger automatically goes into a trickle charge and will continue to do so until the probe is disconnected.

Battery Tips

NiCd batteries have several characteristics that can affect both their performance and operating life. The following tips advise you how to take advantage of these characteristics to get the most out of your probe’s battery.

• Although NiCd batteries are rated for operation in temperatures from -20 EC to +65 EC (-4 EF to +140 EF), operating the probe in extreme temperatures will reduce operating time significantly. The optimum operating temperature range for these batteries is +20 EC to +30 EC (+68 EF to +86 EF).

• The battery in the HI-4455 probe does not require periodic "deep discharges" to reverse the capacity depleting "memory effect" caused by repeated shallow discharges; however, undercharging can reduce battery capacity. Therefore, after the charging procedure is complete, be sure that the battery is fully charged before resuming field operation.

• If the battery exhibits low terminal voltage during charging, or if it appears unable to acquire or maintain an appreciable charge, individual cells in the battery may be shorted or damaged. If, for any reason, your battery needs replacement, contact ETSLindgren Customer Service for assistance.

3. OPERATION

This section discusses the theory of operation and the functions of the HI-4455 Isotropic Field Probe. A high-level block diagram (Figure 3) is included to aid the discussion. The objective is to provide information enhancing user understanding of the design of this probe.

SYSTEM THEORY

The HI-4455 Broadband Isotropic Electric Field Probe utilizes a microprocessor for intelligent operation and control. The probe's selfcontained power supply employs a 3.6 VDC NiCd battery, which provides up to 17 hours of continuous operation.

For each axis, the probe measures the radio frequency signal level and generates a linearized reading of the measurement. A vector addition is performed on these three readings: the result is transmitted to the readout over glass fiber optic cables. See "Probe Operation" for a more detailed explanation of the functioning of the HI-4455.

The probe relays data to the readout via either a short form or long form output word. See Appendix B for details on both output word formats.

For some limited, specialized applications, you may use any computer with an RS232 serial port to communicated directly with the HI-4455 via ETS-Lindgren’s optional HI-4413P Fiber Optic/RS232 Interface.

PROBE OPERATION

Receiver commands to the probe consist of the following:

• Send reading

• Read battery voltage

• Zero

• Set sleep timer

• Switch range

• Read temperature

• Enable axis

The signal flow within the probe is shown in the block diagram. To measure field strength, three mutually orthogonal dipole antennas

(one per axis) are used to provide an isotropic response to the ambient field. The signal from each axis is fed to a Schottky diode detector operating in its Square-Law region. After filtering, the signals generated by each axis are added vectorially: the resultant is fed to the instrumentation amplifier, whose output feeds the selectable range/offset stage.

NOTE: The HI-4455 does not allow the option of measuring on an individual axis: all three axes are active at all times.

For each of the four ranges, the selectable range and offset stage provides a coarse analog zero for the measured signal. The output of the range/offset stage is fed to the A/D multiplexer, then to the analog-todigital (A/D) converter itself.

After acquiring the composite three-axis signal, the microprocessor commands the A/D multiplexer to read the battery voltage and temperature sensing lines.

Data from the A/D converter is fed to the microprocessor, which transmits it to the receiver.

The EEPROM stores all calibration data for the probe.

PROBE POWER SUPPLY

A sealed rechargeable 3.6 VDC NiCd battery, which drives both the analog and digital power supplies, powers the HI-4455 probe: separate power sources provide isolation between the analog and digital circuitry. With the probe switch in the ARM position, battery voltage is applied to the power switch, which routes this voltage to the power supply, enabling the microprocessor. A timer circuit controls the power switch. The timer monitors the fiber optic connector input line to determine whether the probe has received a command during a specified period (several seconds). If no command is received during this period, the timer signals the power switch to disable the power supply and the microprocessor. In essence, the probe goes dormant to conserve battery power: only the fiber optic input circuitry remains active in order to detect new commands. When the next command from the receiver reaches the probe, power is reapplied automatically and the processor is reactivated, "waking up" the probe.

NOTE: The probe uses volatile random access memory (RAM). If, for any reason, power to the probe is lost, the probe must be re-zeroed.

ZEROING

When the receiver sends a zero command, the probe must be in a zero field environment. This is because the zero command causes the multiplexer (via the processor) to perform a normal read cycle on the composite axis signal. This procedure is executed for all ranges. When the processor receives all the zero-field values, it stores them in a special register; these values are subtracted from all subsequent measurements. Therefore, a probe which is zeroed while it is not in a zero field environment will give erroneous readings.

APPLICATION CONSIDERATIONS

The following subsections contain information designed to help you maximize the effectiveness of the HI-4455.

Out-of-Band Considerations

Although the HI-4455 is nominally rated for operation from 200 kHz to 40 GHz, it responds to signals both above and below these frequencies. Any probe response to out-of-band frequencies must be compensated for when zeroing the probe.

Resolution Limitations

Limitations in probe resolution may result in a non-zero reading when the receiver is zeroed. If this occurs, it does not necessarily mean either that there is a problem with the receiver or that your readings are inaccurate. Receiver linearity is specified as + 0.5 dB full scale: in addition, the variance of the A/D converter is + 2 least significant bits. When using the most sensitive range on a given probe, these specifications create the possibility that, under zero field conditions, the receiver may display a non-zero value.

Probe Support Structures

It is very important to keep conductive objects away from the HI-4455. Any such objects in the proximity of the probe may distort the near field and compromise measurement accuracy. If your application requires measurements from a fixed position, always mount the probe on a nonmetallic platform, using non-metallic screws.

1.0 Description

The 491198-36 NiCd Battery Fast Charger is a dual power source battery charger. It charges 3.6 volt 1400 mAH NiCd batteries and is powered by 120-240 Vac line power or 12.5 Vdc. The 491198-36 uses a

-(dV)/(dT) (negative delta V) technique to determine when the battery is fully charged, typically one hour. With this technique, the charge state of the battery has no effect other than shortening the charge time.

Housed in a rugged enclosure, power enters the battery charger through a power entry module, which contains the fuses, or an optional cigarette lighter plug adapter. LEDs and the label on the front face of the unit provide operating status. The battery charger connects to the device being charged through a short cord terminated with a power jack.

An integrated circuit within the charger monitors the battery voltage and controls the charging functions according to the charge state of the battery.

4.0 OPERATING INSTRUCTIONS

The 491198-36 battery charger is intended to charge the 3.6 volt NiCd batteries, either in the lab or in the field.

INPUT POWER REQUIREMENTS

The 491198-36 charger may be powered by standard line voltage (110 240 Vac, 50 - 60 Hz) or by an optional automobile cigarette lighter plug (12.5 Vdc), see specifications. The AC power entry module contains a fuse.

FUSE REPLACEMENT

If a fuse has blown, it must be replaced with the same type and value or an unsafe condition may result. Refer to Figure 2 for fuse replacement.

The fuse is contained in the fuse drawer in the power input module. To access the fuse, use a screwdriver to pry the drawer open and remove it from the module. The drawer holds two fuses; the fuse towards the outside of the drawer is a spare.

After the fuse has been replaced, slide the fuse drawer back into the module. Make sure that it snaps securely into its locked position.

NEVER attempt to change the fuse with the

battery charger plugged in.

CHARGING A BATTERY

After connecting the battery charger to a proper power source, the battery charger simply plugs into the charger jack on the HI-6005. The HI-6005 must be turned off or the battery will not charge.

NEVER attempt to recharge a non-rechargeable

battery.

CHARGING INDICATORS

There are five LEDs located on the front of the charger that provide operating information to the user.

The “POWER ON” LED (green) will remain illuminated as long as the charger is plugged into the AC power source.

If the charger does not detect a battery, the “NO BATTERY” LED (amber) light will illuminate.

When the charger does detect the unit’s battery, the “PENDING” LED (amber) light illuminates while the charger qualifies the battery for fast charge. If the voltage is below the safe fast charge level, the battery is charged in the pulse trickle mode.

When the voltage is at a safe level the charger will switch to the fast charge mode and the “CHARGING” LED (amber) light illuminates.

When charging is complete, the charger switches back to the pulse trickle mode and the “COMPLETE” LED (green) light will illuminate. The device can be left on the charger in this maintenance mode indefinitely.
