More info

The 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 thermocouple and diode power sensors.
HP-IB capability is standard.

Features
Frequency Range: 100 kHz to 110 GHz, sensor dependent
Power Range: 70 tp +44 dBm (100 pW to 25W),
sensor dependent (uses HP 8480 Series power sensors)
Accuracy:
Single channel: ±0.5% (watt mode) or ±0.02 dB (dBm mode)
Dual channel: ±1% (watt mode) or ±0.04 dB (dBm mode)
Zeroing: Automatic, ±0.5% of full scale on most sensitive range
