1 GENERATOR
The GENERATOR menu sets up all steady-state Generator parameters.
1.1 { AMPL }
AMPLitude. This is the rms amplitude of the ac component of the Generator output, in
the range 0V to 10.23Vrms* with a resolution of 10mV.
1.2 { FREQ }
FREQuency. The frequency can be set in the range ImHz to 20kHz with a maximum
resolution of l in 4000. To step the frequency automatically use the SWEEP menu.
1.3
{
BIAS
}
BIAS. This is the steady dc offset of the Generator output, in the range –10.23Vdc* to
+10.23Vdc*, with a resolution of 20mV. It is useful for setting a quiescent operating
point in the system under test, or cancelling offsets in the system.

Generator BIAS and FREQ .
* Note : The peak output of the Generator, set by the combination of AMPL and BIAS,
cannot exceed ±15V.
1.4 { MOD }
MODulation facility. The default setting is [off]. More information is in Chapter 10.
1.5
{
SYNC
}
SYNChronizer facility. The default setting is [off]. More information is in Chapter 10.
NOTE
: In addition to the sine wave output of the generator, it is possible to select
square wave or triangular wave. However, this can only be done by remote command.
See Chapter 8, Section 5. The amplitude, frequency, and bias parameters are equally
applicable to all three waveforms.
