I use this as my ‘reference’ power meter. Disconnect Sensor from Power Ref output.

Providing the finest test equipment solutions since 1992

Recommended for use with the Series Power Sensors. The A needs powering up occasionally to recharge the battery.

The A is a sophisticated microprocessor controlled dual channel power meter which can measure ratio and difference of power levels from 2 different sources. It measures absolute power in Watts or manua, and relative power in dB. Top view with cover removed.

Mznual A has a 3V 0. Rear Panel Sensor Connector and additional reference oscillator with rear panel output. Important measurement contributions are a programmable digital filter for optimizing resolution and measurement speed, independent offset in dB values for each channel, 0. Top PCB hinges up. The programmable digital averaging filter gives the user control over the inherent tradeoff between speed and accuracy.

The battery maintains the supply voltage to the RAM. Initial power up display. Switch off Power Ref, check Oscillator light is off. January A Quick Calibration Procedure: The AUTO filter mode is usually maual for fully settled readings with 0.

Complete interrupt capability with flexible SRQ operation optimizes the efficiency of program execution in automatic systems. A HP Manual was downloaded from the Web. The power reference output and calibration controls are used np calibrate the particular power sensor in use.

4338a November Checking all the specialist batteries in my test equipment, see Batteries In Test Equipment. The compact front panel is designed to save space in rack mounted systems, while the dual channel design allows simple measurements of the ratio and difference of power levels from two separate sensors.

Less digital averaging leads to faster but noisier readings if speed is the critical issue.

Bottom view with cover removed. Up to 19 different operating states of the meter can be stored into non-volatile memory for later recall. Compatible with the HP series of thermocouple and diode sensors, the power and frequency 483a of the meter extends from dBm to 44 dBm and from kHz to 50 GHz.

Welcome to Azur Electronics. Display with no sensors connected.

HP A Power Meter

All measurement modes are programmable including zeroing, calibration, and Cal Factor. Press Zero key and wait for routine. Up to 19 different operating states of the meter can be stored into non-volatile memory for later recall.
