Residual Measurement Fundamentals
The Calibration Options
Synthesized Residual
Measurement using
Beatnote Cal
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.
Procedure 1. Connect circuit as per Figure8-12onpage8-19, and tighten all
connections.

2. Offset the carrier frequency of one synthesizer to produce a beatnote for
cal.
Table 8-5 Beatnote Frequency Ranges
Carrier Frequency

Range
<500kHz 10Hzto10kHz
<5 MHz 10 Hz to 100 kHz
<50 MHz 10 Hz to 1 MHz
<250MHz 10Hzto10MHz
>250MHz 10Hzto50MHz
or 1/2 the frequency range of the configured analyzer, or
whichever is lower.
