Example 2: Setting the Output Amplitude.
Use the AMPTD key, of the ENTRY group, to set the out-
put voltage amplitude as follows:
1. Press AMPTD, and note that the instrument displays
the existing amplitude
and allowed amplitude
range.
2. To enter a completely new amplitude value in p-p
units, press the keys for the desired numeric value,
then press V or mV, as required. For example, to en-
ter a 30mV p-p amplitude, press the following three
keys: 3 0 mV.
3. To simply modify the existing amplitude value, use
the cursor keys and the MODIFY knob to set the
value as required.
4. Press DSPL to return to normal display.
Example 3: Programming
the DC Offset
The OFFSET key allows you to set the DC or average level
of the main synthesizer output waveform, as in the fol-
lowing example:
1. Press OFFSET and note that the instrument displays
the existing offset value and allowed range.
2. Either press the numeric keys for the desired offset
value, or use the MODIFY knob and/or cursor keys
to change the value.
3. Press DSPL to return to normal display.
Example 4: Setting Phase Shift
The PHASE key allows you to set the amount of phase
shift, in degrees, of the main synthesizer output wave-
form, as in the following example:
1. Press PHASE and note that the instrument displays
the existing phase value and the allowed range.
2. Enter the desired phase shift value, or use the MOD-
IFY KNOB and/or cursor keys to change the existing
value.
3. Press DSPL to return to normal display.
