In this mode the 2 IF output is passed through a log amp and the log envelope of the IF signal is sent to
the rear panel. The open circuit output level varies by about 25 mV per dB, with a top-of-screen signal
producing about 1.6 Volts. The output impedance is nominally 50 ohms.
This mode is intended to meet the same needs as Option E4440A-H7L Fast Rise Time Video Output on
the Agilent E4440A PSA Series, allowing you to characterize pulses with fast rise times using standard
measurement suites on modern digital scopes.

In this mode nothing comes out of the "AUX IF OUT" connector on the rear panel. The connector
appears as an open-circuit (that is, it is not terminated in any way).

I/Q Guided Calibration

Calibrating the Baseband I/Q ports requires several steps and manual connections. The Guided
Calibration will interactively step a user through the required steps, displaying diagrams to help with the
connections. The steps will vary depending on the setup.
In the Guided Calibration windows, the date and time of the last calibration are displayed. If any of the
items listed are displayed in yellow, this indicates that the calibration for that item is inconsistent with

The output is off during an alignment but not during a marker count, and is not
blanked during retrace (after a sweep and before the next sweep starts).
