FUNCTIONS FOR RECEIVE

5

Displays signals within the specified frequency range. The selected frequency band conditions can be observed at a glance when using this mode.

qPush EXIT/SET several times to close a multi-func- tion screen, if necessary.

wPush [F-1•SCOPE] to select the scope screen. e Push [F-5•CENT/FIX] to select the fixed mode.

FIX ” is displayed when fixed mode is selected. r Push [F-2•ATT] several times to activate an attenu-

ator or turn the attenuator OFF.

10, 20 and 30 dB attenuators are available.

Push and hold [F-2•ATT] for 1 sec. to turn OFF the at- tenuator.

tPush [F-3•MARKER] several times to select the marker for transmit frequency or turn the marker OFF.

R ” displays the marker at the receive frequency. (al- ways displayed)

T ” displays the marker at the transmit frequency.

“<<” or “>>” appears when the marker is out of range.

The spectrum scope shows the transmit signal wave- form while transmitting. This can be deactivated in scope set mode. (p. 5-5)

The spectrum scope shows the peak level holding func- tion. Peak levels are displayed in the background of the current spectrum in a different color until the receive fre- quency changes. This can be deactivated and the wave- form color can be set in scope set mode. (p. 5-5)

yPush [F-4•HOLD] to freeze the current spectrum waveform.

HOLD ” appears while the function is in use.

The peak hold function can be deactivated in scope set mode.

uPush EXIT/SET to exit the scope screen.

NOTE: If a strong signal is received, a ghost wave- form may appear. Push [F-2•ATT] several times to activate the spectrum scope attenuator in this case.

The scope bandwidth can be specified for each op- erating frequency band independently in scope set mode. (pgs. 5-6 to 5-8)
