Initial S/W Revision A.04.00
Second IF
In this mode the 2nd IF output is routed to the rear panel connector. The annotation on the key
shows the current 2nd IF frequency in use in the analyzer.
The frequency of the 2nd IF depends on the current IF signal path as shown in the table below:
IF Path Selected Frequency of “Second IF” Output
10 MHz 322.5 MHz
25 MHz 322.5 MHz
40 MHz 250 MHz
140 MHz 300 MHz
The signal quality, such as signal to noise ratio and phase noise, are excellent in this mode.

Initial S/W Revision A.04.00
Arbitrary IF
In this mode the 2nd IF output is mixed with a local oscillator and mixer to produce an arbitrary
IF output between 10 MHz and 75 MHz with 500 kHz resolution. The phase noise in this mode
will not be as good as in Second IF mode.
The IF output frequency is adjustable, through an active function which appears on the Arbitrary
IF selection key, from 10 MHz to 75 MHz with 500 kHz resolution.
The bandwidth of this IF output varies with band and center frequency, but is about 40 MHz at
the –3 dB width. When the output is centered at lower frequencies in its range, signal frequencies
