[. . . ] ·" " displays the marker at the sub readout frequency. · "<<" or ">>" appears when the marker is out of range. · The spectrum scope shows the transmit signal waveform while transmitting. 5-4) · 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 receive frequency changes. This can be deactivated and the waveform color can be set in scope set mode. 5-5) · Observed indication example i Push [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. o Push [EXIT/SET] to exit the scope screen. Push [F-2·ATT] several times to activate the spectrum scope attenuator in this case. They are generated in the internal scope circuit and do not indicate a transceiver malfunction. 5-2 FUNCTIONS FOR RECEIVE 5 D Fix mode Displays signals within the specified frequency range. The selected frequency band conditions can be observed at a glance when using this mode. [F-2·ATT] [F-4·HOLD] [F-5·CENT/FIX] q Push [EXIT/SET] several times to close a multifunction screen, if necessary. · The set color is indicated in the box beside the RGB scale. Select the sweeping speed for the ±2. 5 kHz span selection from SLOW, MID and FAST. NOTE: The waveform may be displayed incorrectly with "FAST" setting. Select the sweeping speed for the ±5 kHz span selection from SLOW, MID and FAST. NOTE: The waveform may be displayed incorrectly with "FAST" setting. Select the sweeping speed for the ±10 kHz span selection from SLOW, MID and FAST. Select the sweeping speed for the ±25 kHz span selection from SLOW, MID and FAST. 5-5 5 FUNCTIONS FOR RECEIVE D Scope set mode (continued) Select the sweeping speed for the ±50 kHz span selection from SLOW, MID and FAST. Select the sweeping speed for the ±100 kHz span selection from SLOW, MID and FAST. Select the sweeping speed for the ±250 kHz span selection from SLOW, MID and FAST. Set the scope edge frequencies for fix mode scope with below 1. 6 MHz band selection. · Set the frequencies within 0. 030 to 1. 600 MHz range in 1 kHz steps. Up to 500 kHz band width can be specified, so either edge frequency will be set to the difference between higher and lower frequencies become 5 to 500 kHz automatically while setting another edge frequency. Set the scope edge frequencies for fix mode scope when 1. 6 to 2 MHz band is selected. · Set the frequencies within 1. 600 to 2. 000 MHz range in 1 kHz steps. Set the scope edge frequencies for fix mode scope when 2 to 6 MHz band is selected. · Set the frequencies within 2. 000 to 6. 000 MHz range in 1 kHz steps. Up to 500 kHz band width can be specified, so either edge frequency will be set to the difference between higher and lower frequencies become 5 to 500 kHz automatically while setting another edge frequency. Set the scope edge frequencies for fix mode scope when 6 to 8 MHz band is selected. · Set the frequencies within 6. 000 to 8. 000 MHz range in 1 kHz steps. Up to 500 kHz band width can be specified, so either edge frequency will be set to the difference between higher and lower frequencies become 5 to 500 kHz automatically while setting another edge frequency. 5-6 FUNCTIONS FOR RECEIVE 5 D Scope set mode (continued) Set the scope edge frequencies for fix mode scope when 8 to 11 MHz band is selected. · Set the frequencies within 8. 000 to 11. 000 MHz range in 1 kHz steps. Up to 500 kHz band width can be specified, so either edge frequency will be set to the difference between higher and lower frequencies become 5 to 500 kHz automatically while setting another edge frequency. Set the scope edge frequencies for fix mode scope when 11 to 15 MHz band is selected. · Set the frequencies within 11. 000 to 15. 000 MHz range in 1 kHz steps. Up to 500 kHz band width can be specified, so either edge frequency will be set to the difference between higher and lower frequencies become 5 to 500 kHz automatically while setting another edge frequency. Set the scope edge frequencies for fix mode scope when 15 to 20 MHz band is selected. · Set the frequencies within 15. 000 to 20. 000 MHz range in 1 kHz steps. Up to 500 kHz band width can be specified, so either edge frequency will be set to the difference between higher and lower frequencies become 5 to 500 kHz automatically while setting another edge frequency. Set the scope edge frequencies for fix mode scope when 20 to 22 MHz band is selected. · Set the frequencies within 20. 000 to 22. 000 MHz range in 1 kHz steps. Up to 500 kHz band width can be specified, so either edge frequency will be set to the difference between higher and lower frequencies become 5 to 500 kHz automatically while setting another edge frequency. Set the scope edge frequencies for fix mode scope when 22 to 26 MHz band is selected. · Set the frequencies within 22. 000 to 26. 000 MHz range in 1 kHz steps.
