SPAN

This field is the value for the frequency range covered by the GSP-810 as it

sweeps its receiver. This span value may be changed by the

SPINNER

to roll

through the list of valid spans.

The range of valid entries is 2 kHz / division through 100 MHz / division plus zero

span (0 Hz / div). If changing SPAN will cause Center Frequency to change, the

“Limt” message will appear on LCD. It means that the SPAN has exceeded the

frequency range for Center Frequency setting. For example, if the Center

Frequency is 25MHz and the Span is changed from 5MHz to 10MHz, a “Limt” will

appear because the start frequency of span has exceeded the frequency range of

GSP810.
