3. Set the 2400 to each frequency listed on the data sheet and verify that the counter reads the set
frequency plus or minus the counter resolution.
4. Connect the 2400 RF Output to the 500 MHz to 26.5 GHz input on the counter and continue with
the divider tests. To check that the multipliers are functioning properly, refer to the test data
sheet and program each of the listed frequencies into the 2400 by entering (for example) [CW] [2]
[0] [0] [1] [MHZ]. For each listed frequency, the counter should read the entered frequency ±1 Hz,
plus or minus the counter resolution. Ignore all frequencies outside the range of the instrument
under test.
4.4.2.3 Spurious Signal Tests
4.4.2.3.1 Description
The output of the 2400 is connected to a spectrum analyzer. Various frequencies are selected and the
analyzer tuned to determine the presence of either harmonically or non-harmonically spurious sig-
nals.
4.4.2.3.2 Equipment Required
• UUT
• Spectrum Analyzer
• Coaxial Cable

4.4.2.3.1 Procedure
1. Connect the equipment as shown in Figure 4-2. Allow the equipment to warm up for at least 30
minutes. Press [Frequency] soft-key in the CW menu on the 2400 and enter the test frequency
