   The Agilent/HP 438A power meter is a dual-channel power meter designed specifically for ATE systems. The compact front panel saves critical rack space, while the dual-channel design allows simple and accurate measurements of the ratio and difference of power levels from two separate sensors. This meter is compatible with the 8480 series of power sensors. GPIB capability is standard on the 438A.

Features

  • Two power sensors for multi-port measurement
  • Ratio mode for measuring gain compression
  • Programmable high and low power limits for unattended power monitoring
  • Frequency: 100 kHz to 26.5 GHz
  • Power Range: -70 to +44 dBm
  • Dynamic Range: 50 dB
  • Measurement Modes: A, B, A-B, B-A, A/B, B/A

   Important measurement contributions are a programmable digital filter for optimizing resolution and measurement speed, independent offset (in dB) values for each channel, 0.001 dB resolution available, and a power difference mode for displaying absorbed power in transmission lines.  Up to 19 different operating states of the meter can be stored into non-volatile memory for later recall.

   The programmable digital averaging filter gives the user control over the inherent tradeoff between speed and accuracy.  The AUTO filter mode is usually adequate for fully settled readings with 0.01 dB resolution.  Less digital averaging leads to faster but noisier readings if speed is the critical issue.
