End frequency (Ch. END)
Press the Ch. END soft key (right key below the LCD) to make the end frequency display
appear in reverse contrast. Enter a desired frequency using the numeric keys, which is the
highest frequency spread you wish to monitor, followed by the MHz key to confirm.
Marker and main frequency marker operation
When the channel scope mode is activated, monitoring begins on the start frequency.
Press the FUNC key followed by the FREQ. key and rotate the dial knob to move the white
marker onto the signal of your interest, then press the MK.F key. The yellow receive
marker moves to the nominated position and the SR2000A monitors the selected
frequency.
[Note]
The channel scope mode functions only in the VFO mode. Moreover, if the VFO is switched,
setting information will be lost and the operation mode will change to spectrum analyzer
mode
The end frequency (Ch. END) is confined by the following formula:
(Ch. START) + [(Ch. STEP) x 160]
(Ch. START) + 5 MHz
(Ch. START) + > 0.16 MHz
For this reason, if you do not enter an end frequency, the SR2000A will automatically
select an appropriate end point.
Invalid entry for the end frequency will be alerted with a beep and the closest possible
valid frequency will be automatically chosen by the SR2000A. The same happens with any
invalid frequency entry.
6-3 Marker functions
The SR2000A has a marker function. The marker is often used to obtain the value of a
frequency of interest. In addition to the instantaneous reading, it provides peak detection
and continuous peak detection. Press the FUNC key followed by the MK.F key to place the
SR2000A in marker mode operation.
INSTANTANEOUS
The marker function operates in the WSP mode and the memory channel mode (except
MK.F mode).
Instantaneous reading (Marker : MKR)
This feature is useful for many applications. The marker can be moved sideways by rotating
the dial knob. The LCD displays the frequency and signal strength reading where the marker
is positioned.
