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.
