PAUSING THE WAVEFORM DISPLAY You can pause the waveform display on the Bandscope screen. 1 Press [PAUSE] (F5) to pause the displayed waveform. • "PAUSE" appears while the waveform display is paused. • If [PAUSE] (F6) is unavailable in the key guide, press [MORE] (F1). BANDSCOPE 7 CHANGING THE ATTENUATOR FOR THE BANDSCOPE If the target signal cannot easily be distinguished on the Bandscope screen due to excessive input signal even after the adjustment of the reference level, change the attenuator for the bandscope to attenuate the bandscope input level. 1 Press [ATT] (F5) to select an attenuator. • Each time you press [ATT] (F5), the level cycles as follows: Off > 10 dB > 20 dB > 30 dB. The attenuated value appears on the upper right side of the grid. • Pressing and holding [ATT] (F5) cycles through the attenuation in the reversed sequence. • The default is "Off". • If [ATT] (F5) is unavailable in the key guide, press [MORE] (F1). • Pressing any key other than [MORE] (F1) and [MARKER] (F7) releases the pause of the waveform display. AVERAGING THE WAVEFORM DISPLAY ON THE BANDSCOPE If the waveform display on the bandscope is averaged, the waveform transition on the display becomes gradual, hence intermittent signals such as Morse code can easily be observed. 1 Press [AVE.] (F6) to change the averaging level. • Each key press cycles the averaging level through "Off" (no averaging) > "1" (minimum) > "2" > "3" (maximum) > "Off". The averaging level appears on the upper right side of the grid. • Pressing and holding [AVE.] (F6) cycles the averaging level in the reversed sequence. • The default is "2" in SSB/AM/FM mode and "1" in CW/FSK/ PSK mode. • If [AVE.] (F6) is unavailable in the key guide, press [MORE] (F1). • The averaging level can be configured separately in SSB/ AM/FM mode and CW/FSK/PSK mode. Note: ◆◆Changing of the attenuation for the bandscope does not influence the receive sensitivity. ◆◆The setting value of the bandscope attenuator is stored for each amateur band. Contents Index 7-9
