RECEIVE AND TRANSMIT
■Spectrum scope screen
This function allows you to display the relative
strengths of signals around the center frequency. The
span can be set to ±12.5 kHz, ±25 kHz, ±50 kHz and
±100 kHz. Ideal for monitoring band conditions in an
instant.
qPush [EXIT/SET] several times to close a multi-
function screen, if necessary.
wPush [(F-1)SCOPE] to select the scope screen.
ePush [(F-1)SPAN] several times to select the
scope span.
rPush [(F-2)ATT] several times to activate an atten-
uator or turn the attenuator OFF.
•10, 20 and 30 dB attenuators are available.
tPush [(F-3)MARKER] several times to select the
marker (sub readout or transmit frequency) or turn
the marker OFF.
•“TX MARKER” displays the marker at the transmit fre-
quency.
•“SUB MARKER” displays the marker at the sub readout
frequency.
yPush [(F-4)HOLD] to freeze the current spectrum
waveform.
•“HOLD” appears while the function is in use.
uPush [EXIT/SET] to exit the scope screen.
•Spectrum scope during transmitting
The spectrum scope shows the transmit signal wave-
form while transmitting. This can be deactivated if de-
sired.
When “OFF” is selected, the spectrum scope holds
the received waveform while transmitting and does
not show the transmit waveform.
qCall up the scope screen as described at left.
wPush [(F-5)SET] to select the spectrum scope set
mode.
ePush [(F-1)∫] to select the “Scope during Tx” item.
rRotate the tuning dial to display the spectrum
scope while transmitting or not.
tPush [EXIT/SET] to exit spectrum scope set mode.
•Maximum level hold function
The spectrum scope shows the peak level holding
function. Peak levels are displayed in the background
of the current spectrum in a different color until the re-
ceive frequency changes. This can be deactivated if
desired.
qCall up the scope screen as described at left.
wPush [(F-5)SET] to select the spectrum scope set
mode.
ePush [(F-2)√] to select the “Max Hold” item.
rRotate the tuning dial to turn the peak level holding
function ON or OFF.
tPush [EXIT/SET] to exit spectrum scope set mode.
If a strong signal is received, a ghost waveform
may appear. Push [(F-2)ATT] several times to acti-
vate the spectrum scope attenuator in this case.
