Rear Panel Sensor Connector and additional reference oscillator with rear panel output. January A Quick Calibration Procedure: Display with no sensors connected. Up to 19 different operating states of the meter can be stored into non-volatile memory for later recall. November Checking all the specialist batteries in my test equipment, see Batteries In Test Equipment. A HP Manual was downloaded from the Web.

The programmable digital averaging filter gives the user control ho the inherent tradeoff between speed and accuracy. Welcome to Azur Electronics. 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.

A Dual Sensor Power Meter [Obsolete] | Keysight (formerly Agilent’s Electronic Measurement)

Up to 19 different operating states of the meter can be stored into non-volatile memory for later recall. Bottom view with cover removed. Important measurement contributions are a programmable digital filter for optimizing resolution and measurement speed, independent offset in dB values for each channel, 0. Less digital averaging leads to faster but noisier readings if speed is the critical mahual. The AUTO filter mode is usually adequate for fully settled readings with 0.

I use this as my ‘reference’ power meter.

Initial display lights all segments. Recommended for use with the Series Power Sensors. It measures absolute power in Watts or dBm, and relative power in dB. The battery maintains the supply voltage to the RAM.

The power reference output and calibration controls are used to calibrate the particular power sensor in use. Initial power up display. The A has a 3V 0. Disconnect Sensor from Power Ref output. All measurement modes manjal programmable including zeroing, calibration, and Cal Factor. The A is a sophisticated microprocessor controlled dual channel power meter which can measure ratio and difference of power levels from 2 different sources.

438A Dual Sensor Power Meter

Compatible with the HP series of thermocouple and diode 483a, the power and frequency range of the meter extends from dBm to 44 dBm and from kHz to 50 GHz.

Top PCB hinges up. Switch off Power Ref, check Oscillator light is off. Top view with cover removed. Press Zero key and wait for routine. Complete interrupt capability with flexible SRQ operation optimizes the efficiency of program execution in automatic systems. The A needs powering up occasionally to recharge the battery.
