Switch off Power Ref, check Oscillator light is off. Press Zero key and wait for routine. 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 dBm, and relative power in dB. The power reference output and calibration controls are used to calibrate the particular power sensor in use.

Up to 19 different operating states of the meter can be stored into non-volatile memory for later recall. Bottom view with cover removed. Top view with cover removed. View Cart My Account.

HP A Power Meter

Up to 19 different operating states of the meter can be stored into non-volatile memory for later recall. Initial display lights all segments. A HP Manual was downloaded from the Web. Rear Panel Sensor Connector and additional reference oscillator with rear panel output.

The AUTO filter manuql is usually adequate for fully settled readings with 0.

November Checking all the specialist batteries in my test equipment, see Batteries In Test Equipment. Initial power up display. Less digital averaging leads to faster but noisier readings if speed is the critical issue. The A needs powering up occasionally to recharge the battery.

January A Quick Calibration Procedure: Disconnect Sensor from Power Ref output. Recommended for use with the Series Power Sensors. Important measurement contributions are a programmable digital filter for optimizing resolution and measurement speed, independent offset mnual dB values for each channel, 0.

Agilent / HP 438A Dual Channel Power Meter

The battery maintains the supply voltage to the RAM. Complete interrupt capability with flexible SRQ operation optimizes the efficiency of program execution in automatic systems.

Display with no sensors connected. All measurement modes are programmable including zeroing, calibration, and Cal Factor. Manjal programmable digital averaging filter gives the user control over the inherent tradeoff between speed and accuracy. The A has a 3V 0.

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. I use this as my ‘reference’ power meter. The compact front panel is designed to save space in rack mounted systems, while the dual channel design allows msnual measurements of the ratio and difference of power levels from two separate sensors.
