Function key:
Function keys for 2nd page of the main function key
• AF Level function key — The same as the AF Level function keys at the 1st page of the main function key
• RX RF Frequency function key:
[Incremental Step Value] F7 Sets the step value to up/down the RF frequency of the built-in signal generator (SG)
of the MT8801B with [Step] keys.
1 Hz ≤ Set value ≤ 3 GHz, 1 Hz step
Initial value: 1 MHz
[Relative On Off] F8 Displays the relative value with the reference value that is the set value when this key
is pressed.
Initial value: Off
When the frequency is set with numeric keys in Relative On mode, it becomes the
actual output frequency (not relative value).
Relative displayed value = Set value by numeric keys - value when this key is pressed
[Channel] F9 Changes the channel number. (See para. 4.4 for changing method.)
[Back Screen] F12 Returns to the Setup Common Parameter screen.
• RX RF Level function key:
1st page
[Incremental Step Value] F7 Sets the step value to up/down the RF level of signal generator with [Step] keys.
Range: 0.1 dB ≤ Set value ≤ 80.0 dB, 0.1 dB step
Initial value: 1.0 dB
[Relative On Off] F8 Displays the relative value with the reference value of 0 dB that is the level when this
key is pressed.
Initial value: Off
When the level is set with numeric keys in Relative On mode, it becomes the actual
output level (not relative value).
Relative displayed value = Set value by numeric keys - value when this key is pressed
[Unit EMF TERM] F10 Selects the RF level unit of the open voltage (EMF, dBµ), terminated voltage
(TERM, dBµ).
Level can be set at dBµ display. 30 dBµ EMF = 24 dBµ TERM
Initial value: EMF
[Back Screen] F12 Returns to Setup Common Parameter screen.
Note:
When the unit key [dBµ/V] pressed, it is assumed as “dBµ” for RF level set-
ting, and as “V” for AF level setting.
