HP 438A Manuals

Compatible with the HP series of thermocouple and diode sensors, the manuao and frequency range of the meter extends from dBm to 44 dBm and from kHz to 50 GHz. Recommended for use with the Series Power Sensors.

A HP Manual was downloaded from the Web. Top PCB hinges up. Display with no sensors connected. 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.

Disconnect Sensor from Power Ref output. Initial display lights all segments. November Checking all the specialist batteries in my test equipment, see Batteries In Test Equipment.

Rear Panel Sensor Connector and additional reference oscillator with rear panel output. The A has a 3V 0. 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. Complete interrupt capability with flexible SRQ operation optimizes the efficiency of program execution in automatic systems.

January A Quick Calibration Procedure: Up to 19 different manuaal states of the meter can be stored into non-volatile memory for later recall. View Cart My Account. The A needs powering up occasionally to recharge the battery.

Less digital averaging leads to faster but noisier readings if speed is the critical issue. The A is a sophisticated microprocessor controlled dual channel manua meter which can measure ratio and difference of power levels from 2 different sources.

Important measurement contributions are a programmable digital filter for optimizing resolution and measurement speed, independent offset in dB values for each channel, 0. Press Zero key and wait for routine. Switch off Power Ref, check Oscillator light is off. The power reference output and calibration controls are used to calibrate the particular power sensor in use.

438A Dual Sensor Power Meter

All measurement modes are programmable including zeroing, calibration, and Cal Factor. The AUTO filter mode is usually adequate for fully h readings with 0.

I use this as my ‘reference’ power meter. The programmable digital averaging filter gives the user control over the inherent tradeoff between speed and accuracy.

Top view with cover removed. It measures absolute power in Watts or dBm, and relative power in dB. Bottom view with cover removed. Welcome to Azur Electronics.
