Integrated 4-port network analysis and balanced measurements
Internal dual-source for fast measurements of amplifier swept-IMD and mixer/converter fixed-IF measurements
Reversible front panel jumpers for extended dynamic range configuration
Configurable for high power measurements with external components
This 4-port test set option comes with internal dual-source, a reference and test receivers at each test port, and twelve front-panel access loops. The loops provide access to the signal path between (a) the source output and the reference receiver, (b) the source output and directional coupler thru arm and (c) the coupled arm of the directional coupler and the port receiver. The internal second source provides an additional signal (fixed or swept) for two-tone third-order-intercept (TOI) and intermodulation testing of amplifiers, or it can be used as a fast swept-LO signal for fixed-IF testing of mixers and converters. With two sources, source 1 is accessible through test ports 1 and 2, and source 2 is accessible through test ports 3 and 4. It also includes a solid-state internal RF transfer switch in the R1 reference-receiver path. Recommend Option 080.
This option provides the capability to improve instrument sensitivity for measuring low-level signals, to reverse the directional coupler to achieve even more dynamic range, or to add components or other peripheral instruments for a variety of applications.
