Agilent / HP 438A Dual Channel Power Meter
Bottom view with cover removed. Top view with cover removed. Top PCB hinges up. Important measurement contributions are a programmable digital filter for optimizing resolution and measurement speed, independent offset in dB values for each channel, 0.
The AUTO filter mode is usually adequate for fully settled readings with 0. The A needs powering up occasionally to recharge the battery. Disconnect Sensor from Power Ref output. January A Quick Calibration Procedure: Display with no sensors connected. Welcome to Azur Electronics. Recommended for use with the Series Power Sensors. The power reference output and calibration controls are used to calibrate the particular power sensor in use.
All measurement modes are programmable including zeroing, calibration, and Cal Factor. Initial display lights all segments.
HP 438A Manuals
I use this as my ‘reference’ power meter. The battery maintains the supply voltage to the RAM. Up to 19 different operating states of the meter can be stored into non-volatile memory for later recall.
It measures absolute power in Watts or dBm, and manuaal power in dB. Complete interrupt capability with flexible SRQ operation optimizes the efficiency of program execution in automatic systems. Press Zero key and wait for routine. The programmable digital averaging filter gives the user control over the inherent tradeoff between speed and accuracy. The Mabual is a sophisticated microprocessor controlled dual channel power meter which can measure ratio and difference of power levels from 2 different sources.
Initial power up display. 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)
November Checking all the specialist batteries in my test equipment, see Batteries In Test Equipment. The A has a 3V 0. View Cart My Account. 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 range of the meter extends from dBm to 44 dBm and from kHz to 50 GHz. Less digital averaging leads to faster but noisier readings if speed is the critical issue.
Rear Panel Sensor Connector and additional reference oscillator with rear panel output. Switch off Power Ref, check Oscillator light is off.
