BAND SCOPE MODE Band Scope mode searches a frequency range and displays the signal level in real time. The screen displays the frequency increasing in value from left to right, and a signal strength meter displays for signals. You can set the center frequency and frequency range span. In Hold mode, you can monitor the displayed frequency. The scanner rapidly sweeps between the endpoints of the selected frequency range and updates each bar segment with the relative signal strength in each pass. Use the band scope in normal mode (the bars are all updated with the most recent signal strength) or Max Hold mode (the bars update only if there is a stronger signal than one previously stored for the current position). This feature allows you to get a "picture" of spectrum activity across the selected range, identify intermittently active frequencies, check antenna performance, check coax quality, and identify interference. USING BAND SCOPE MODE To start Band Scope mode, press HOLD on any channel or frequency and then press FUNC + sr3/3. This frequency becomes the center frequency. Band Scope mode is assigned to this Search Key (sr3/3) by default. Press pri./No to access the Search Span (SPN), Center Frequency (CF) and Search Step (STP) fields in order. Press L/O to exit. SPN (Search Span) Hz CF (Center Freq) MHz STP (Search Step) Hz NOTE: Band Scope mode can only be activated via the sr3/3 key. Band Scope has the following three modes: • Search (SRCH) • Max Hold Search Mode (MAX) • HOLD (Hold) 48

BAND SCOPE MODE
Band Scope mode searches a frequency range and displays the signal level in real
time. The screen displays the frequency increasing in value from left to right, and
a signal strength meter displays for signals. You can set the center frequency and
frequency range span. In Hold mode, you can monitor the displayed frequency.
The scanner rapidly sweeps between the endpoints of the selected frequency range
and updates each bar segment with the relative signal strength in each pass. Use
the band scope in normal mode (the bars are all updated with the most recent signal
strength) or Max Hold mode (the bars update only if there is a stronger signal than
one previously stored for the current position).
This feature allows you to get a “picture” of spectrum activity across the selected
range, identify intermittently active frequencies, check antenna performance, check
coax quality, and identify interference.
