Test set specifications for Option 011

HP 85046A/B S-parameter test sets

The HP 85046A/B S-parameter test sets provide the capability to measure reflection and transmission char- acteristics (including S-parameters) of two-port devices in either direction with a single connection. The test sets are controlled from the HP 8753ES Option 011 and include a programmable step attenua- tor. The frequency range of the HP 85046A 50-ohm test set is 300 kHz to 3 GHz. The HP 85046A has preci- sion 7-mm connectors. The frequency range of the HP 85046B 75-ohm test set is 300 kHz to 2 GHz. The HP 85046B has 75-ohm type-N(f) connectors. Both connectors can be adapted to other interfaces with the appropriate precision adapters.

A standard HP 85046A/B test set contains a solid-state transfer switch, which allows continuous switching of power from port 1 to port 2 for full two-port error cor- rection. Option 009 replaces the transfer switch with a mechanical switch. This provides about 1.5 dB more power at the test port, but does not allow continuous switching, so the user must initiate updates of all four S-parameters for full two-port error correction. Also, the mechanical switch has relays that will wear out faster than the solid-state switch. Approximate lifetime of the mechanical switch is 1 million cycles.
