4 RECEIVE AND TRANSMIT D Fixed mode Displays signals within the specified frequency range. Conditions on the selected frequency band can be observed at a glance when using this mode. q P ush [EXIT/SET] several times to close a multi- function screen, if necessary. w Push [SCOPE] (F-1) to select the scope screen. e P ush [CENT/FIX] (F-5) several times to select the fixed mode. • " " is displayed when fixed mode is selected. r P ush [ATT] (F-2) several times to activate an attenuator or turn the attenuator OFF. • 10, 20 and 30 dB attenuators are available. • Push and hold [ATT] (F-2) for 1 sec. to turn OFF the attenuator. t P ush [MARKER] (F-3) several times to turn the marker for transmit frequency and/or sub readout frequency ON or OFF. • " " displays the marker at the transmit frequency. • " " displays the marker at the sub readout frequency. • " " displays the marker at the main readout fre- quency.

(p. 68) • The spectrum scope shows the peak level hold func- tion. Peak levels are displayed in the background of the current spectrum in a different color. This can be deac- tivated and the waveform color can be set in scope set mode.

NOTE: If a strong signal is received, a ghost signal may appear. Push [ATT] (F-2) several times to activate the spectrum scope attenuator in this case. The scope bandwidth can be specified for each frequency band independently in scope set mode.

D
Fixed mode
D±splays s±gnals w±th±n the spec±f±ed frequency range.
Cond±t±ons on the selected frequency band can be
observed at a glance when us±ng th±s mode.
q
Push
[EXIT/SET]
several t±mes to close a mult±-
funct±on screen, ±f necessary.
w
Push
[SCOPE] (F-1)
to select the scope screen.
e
Push
[CENT/FIX] (F-5)
several t±mes to select the
f±xed mode.
• “
” ±s d±splayed when f±xed mode ±s selected.
r
Push
[ATT] (F-2)
several t±mes to act±vate an
attenuator or turn the attenuator OFF.
• 10, 20 and 30 dB attenuators are ava±lable.
•
Push and hold
[ATT] (F-2)
for 1 sec. to turn OFF the
attenuator.
t
Push
[MARKER] (F-3)
several t±mes to turn the
marker for transm±t frequency and/or sub readout
frequency ON or OFF.
• “
” d±splays the marker at the transm±t frequency.
• “
” d±splays the marker at the sub readout frequency.
• “
” d±splays the marker at the ma±n readout fre-
quency. (always d±splayed)
• “<<” or “>>” appears when the marker ±s out of range.
•
The spectrum scope shows the transm±t s±gnal wh±le
transm±tt±ng. Th±s can be deact±vated ±n scope set
mode. (p. 68)
•
The spectrum scope shows the peak level hold func-
t±on. Peak levels are d±splayed ±n the background of the
current spectrum ±n a d±fferent color. Th±s can be deac-
t±vated and the waveform color can be set ±n scope set
mode. (p. 68)
y
Push
[HOLD] (F-4)
to freeze the current spectrum
waveform.
• “

•
Push and hold
[HOLD] (F-4)
to clear the current spec-
trum waveform.
u
Push
[EXIT/SET]
to ex±t the scope screen.
NOTE:
If a strong s±gnal ±s rece±ved, a ghost s±gnal
may appear. Push
[ATT] (F-2)
several t±mes to
act±vate the spectrum scope attenuator ±n th±s
case.
The scope bandw±dth can be spec±f±ed for each fre-
quency band ±ndependently ±n scope set mode.
