Examples of Front Panel Programming

You will find these examples on the following pages:

1Setting the output voltage amplitude

2Setting the output frequency

3Setting the overcurrent protection feature

4Generating step, pulse, and list transients

5Programming trigger delays and phase synchronization

6Programming slew rates

7Measuring peak inrush current

8Setting the GPIB address or RS-232 parameters

9Saving and recalling operating states

10Switching between single- and three- phase operation (Agilent 6834B only)

The examples in the ac source Programming Guide are similar to the ones in this section, except that they use SCPI commands.

1 - Setting the Output Voltage Amplitude

NOTE: The maximum voltage that the ac source can output is limited by the peak value of the waveform, which is 425 Vpeak. Since the output is programmed in units of rms volts, the maximum value that can be programmed is dependent on the peak-to-rms ratio of the selected waveform. For a sinewave, the maximum ac voltage that can be programmed is 300 Vrms. For other waveforms the maximum may be different.

Procedure for Single-Phase AC Sources

When you turn on the ac source, the default output shape is a 60 Hz sinewave at 0 Vrms. There is no output from the ac source because the default output state is OFF, as indicated by the Dis annunciator.

Set the output to 120 V rms as follows:

Action

You can set the voltage in any of three ways:

1.On the Function keypad, press Voltage. On the Entry keypad, press 1 2 0 Enter. This is the easiest way to enter an accurate value.

2.On the Function keypad, press Voltage. On the Entry keypad, press ↓ or ° to increment or decrement the existing value. This technique is useful when you are making minor changes to an existing value.
