The output level of the standard signal generator (SSG) is indicated as the SSG's open circuit.
*Displayed on the controller's display.
1 • Set the SSG as;
Frequency : Specifi ed frequency*
Modulation : None
Level : Specifi ed level
2 • Push [SET•SKIP] to store the adjustment value.
3 • Repeat 1–2 for each specifi ed frequency and value for [NS0] to [WS6].
1 • Set the SSG as;
Frequency : Specifi ed frequency*
Modulation : None
Level : Specifi ed level
2 • Push [SET•SKIP] to store the adjustment value.
3 • Repeat 1-2 for each specifi ed frequency and value for [L5L] to [L8H].
1 Set the SSG as;
Frequency : 3 kHz lower than specifi ed frequency*
Modulation : None
Level : +34 dBµ (–73 dBm)
2 • Push [SET•SKIP] to store the adjustment value.
