Input/Output
at the bottom of the bandwidth will “fold”. For example, with a 40 MHz bandwidth (20 MHz half-
bandwidth), and a 15 MHz IF center, a signal –20 MHz relative to the spectrum analyzer center
frequency will have a relative response of about –3 dB with a frequency 20 MHz below the 15 MHz
IF center. This –5 MHz frequency will fold to become a +5 MHz signal at the IF output. Therefore,
lower IF output frequencies are only useful with known band-limited signals.

Fast Log Video
In this mode the 2nd 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.
