5. Install a probe-tip adapter on the probe (optional). This leaves your hands
free to complete the rest of the functional check. See Table 5 on page 11 for
probe-tip adapter information.
6. Connect the probe tip to the open end of the T-BNC connector.
The spectrum analyzer displays an amplitude signal (0 dBm
±
5 dB) as
shown in Figure 8.

To verify the functionality of Channel B, perform the following tasks:
1. Move the probe from Channel A to Channel B.
2. Move the SMA cable from A OUT to B OUT.
NOTE
. The spectrum analyzer will adjust the RF amplitude offset for Channel A
only. To correct the amplitude for Channel B, see Table 6. For example, if you
are using a 5X probe on Channel B, manually apply an amplitude offset
of --14 dB.
