Errors While Attempting Measurements
4 Test System timebase reference not connected.
Verify that you have access to the base station’s reference timebase signal (typically
19.6608 MHz). The reference should be connected to the SYNTH REF IN port on the
rear of the Cellular Adapter. If configured correctly, the REF UNLOCK indicator on
the Cellular Adapter should not be on.
5 Transmitter not turned on.
You must have a means of controlling the cell site equipment, including the ability to
turn on a given transmitter. If your tool (typically a PC) shows the information, verify
that the transmitter is turned on and that it matches the channel entry in step 1.
