E5500 Phase Noise Measurement System Version A.02.00
This calibration option requires two synthesizers of which one must
be tunable such that a beatnote can be acquired. For the system to
calibrate, the beatnote frequency must be within the following ranges
shown in
Table
8-5.
Table 8-5
Frequency Ranges
Carrier Frequency
<500 kHz
<5 MHz
<50 MHz
<250 MHz
>250 MHz
or 1/2 the frequency range of the configured analyzer, or whichever is lower.

Connect circuit as per
2
Offset the carrier frequency of one synthesizer to produce a
beatnote for cal.
3
After the phase noise system reads the beatnote, set the software
to the same carrier frequency.
