SCOPE FUNCTIONS 7 Deleting a Registered Frequency 1 Press F2 [ ]/ F3 [ ] or turn the [MULTI/CH] control to select the frequency to delete. 2 Press and hold F5 [(DELETE)] to delete. Turning ON/OFF Marker Function 1 Press [MENU]. 2 Press F [F.MKR]. • If F [F.MKR] is not displayed, press F [MORE] to display F [F.MKR]. • Pressing F [F.MKR] each time toggles the marker function between ON and OFF. Displaying the Maximum Value in the Waveform The maximum value of the waveform shown on the spectrum scope screen can be displayed to get a better grasp of the signal status. Turning ON/OFF Maximum Value Display Press F1 [MORE] followed by F7 [MAX.HLD]. Pressing F7 [MAX.HLD] each time toggles the maximum value display between ON and OFF. Configuring the Hold Type Select the method of displaying the maximum value of the waveform. Configure in Menu [8-02] "Bandscope Maximum Hold" Setting Value 10 [s] (default)/ Continuous Averaging of Spectrum Scope Waveform Averaging the waveform on the spectrum scope smoothens the changes in the waveform display making it easier to observe the intermittent signals. Press F1 [MORE], then press F6 [AVE.] to switch the averaging level. • Pressing F6 [AVE.] each time switches the selection in the following sequence: "Off" (averaging disabled) → "1" (minimum) → "2" → "3" (maximum) → "Off". The averaging level selected is displayed at the top right corner of the grid. • Pressing and holding F6 [AVE.] each time switches the options in the reverse sequence. • The averaging level can be configured separately for audio mode (SSB/AM/FM (including DATA mode)) and non-audio mode (CW/FSK/PSK). • The default settings of the audio mode and non-audio mode are "2" and "1" respectively. Displaying the TX Signal Waveform A waveform for the TX signal can be displayed when a bandscope for transmission is displayed in the Center mode. Configure in Menu [8-00] "Bandscope Display during TX" Setting Value Off (default)/ On On: Displays the TX waveform in the bandscope while transmission is in progress. Off: Does not display the waveform in the bandscope while transmission is in progress. ● The setting for this function cannot be switched while transmission is in progress. 10 [s]: Maximum value information is cleared after 10 seconds. Continuous: Maximum value information is not cleared. ● The maximum value information is cleared automatically if the range of the span displayed changes regardless of whether "10 [s]" or "Continuous" is selected. Pausing the Waveform Display The waveform display on the bandscope screen can be paused. Press F7 [PAUSE] to pause the waveform display. • When the waveform display is paused, > is . • Pressing F7 [PAUSE] again cancels the paused state. 7-7
