This document introduces the Agilent 85046A/B and 85047A S-Parameter Test Sets, which can improve the speed, accuracy and ease of RF component measurements with the 8753. The set includes a test bench for measuring the magnitude, phase and group delay response of RF components in the 300 kHz to 6 GHz frequency range and measurement software.
The Agilent 85046A/B and 85047A solid‑state switching S‑Parameter test sets are designed for use with the 8753 network analyzer, providing faster, more accurate S‑Parameter measurements and continuous monitoring of forward and reverse parameters. They replace mechanical switches with solid‑state devices, improving reliability for automatic measurement systems.
The document lists detailed specifications such as frequency range, directivity, source match, switch repeatability, DC bias input range, and connector types for each model, and includes supplemental performance characteristics and support information from Agilent Technologies.
| Frequency Range (85046A) | 300 kHz to 3 GHz |
|---|---|
| Directivity (all models) | 235 dB (300 kHz‑1.3 GHz) |
| Switch Repeatability | +0.03 dB |
| DC bias input range (85046A/B) | +30 VDC, +200 mA (up to +500 mA max) |
| DC bias input range (85047A) | +30 VDC, +200 mA (up to +1 A max) |
The 85046A operates from 300 kHz to 3 GHz.
Measurement speed is improved by 160 ms each time the trace is updated for sweeps with 101 points or more.
The switch repeatability is specified as +0.03 dB.
The 85047A accepts +30 VDC and +200 mA without degradation in RF specifications, up to a maximum of +1 A.
