• Modulation function keys:
1st page ----- AF Osc.1 is used only to modulate (Mod) the internal signal generator (SG) in this
device. When the Call Proc. State is “conversation”, it is used for SAT modulation;
so, the frequency, deviation , and On/Off setting cannot be changed.
[AF Osc.1 Frequency] F8 Sets AF Osc.1 frequency (modulation frequency of the internal signal generator).
20.0 Hz ≤ Set value ≤ 20 000.0 Hz, 0.1 Hz step
Initial value: 1 004.0 Hz
(When the same frequency as of AF Osc.2 is specified at Mod, the deviation is ob-
tained by the addition of the respective deviation set value.)
[AF Osc.1 Deviation] F9 Sets the FM deviation of the internal signal generator by the AF Osc.1 output. 0.00
kHz ≤ Set value≤ 40.00 kHz, 0.01 kHz step
Initial value: 8.00 kHz
[AF Osc.1 On Off] F11 Sets the AF Osc.1 output to on and off to set the modulation by AF Osc.1 of the
internal signal generator to on and off.
(When the output is off, the [AF Osc.1 Deviation] F9 key is not displayed, and the
deviation cannot be specified.)
Initial value: On
[Back Screen] F12 Returns to the Setup Common Parameter screen.
2nd page ---- Sets AF Osc. 1 for modulating (Mod) the built-in signal generator (SG) of the
MT8801B, or for AF signal output (AF) from the AF Output connector on the front
panel.
[AF Osc.2 Signal] F7 — Displays the AF Osc.2 Signal menu.
[AF Signal] F7 Selects AF-Osc. 2 signal type of Tone, Noise (ITU-T G.227), or Noise
(White).
When Noise is set, displays “Noise (Noise type)” at the frequency display area.
Initial value: Tone
[Output for Mod AF] F8 Selects the AF Osc.2 signal usage for Mod (SG modulation signal) or AF (AF
signal output from AF Output connector).
Initial value: Mod
[return] F12 Returns to the Modulation menu.
[AF Osc.2 Frequency] F8 In Mod mode, sets the modulation frequency of SG.
In AF mode, sets the frequency of the AF signal output from the AF Output connector.
When the AF Osc. 2 Signal type is Noise, this item disappears.
20.0 Hz ≤ Set value ≤ 20 000.0 Hz, 0.1 Hz step
Initial value: 1 004.0 Hz
[AF Osc.2 Deviation] F9 In Mod mode, sets the FM deviation of SG.
In AF mode, this item disappears.
0.00 kHz ≤ Set value≤ 40.00 kHz, 0.01 kHz step
Initial value: 8.00 kHz
