User Manual 301/302

When the main output state is programmed to ON, the output

connector is connected to the output amplifier through a 50Ω resistor

and an LED near the output connector illuminates. In the OFF

position, the output connector is disconnected from the output

amplifier by means of a mechanical relay. Ensure that voltage is not

applied to the main output connector when the Model 301/302 output

state is programmed to ON.

The query:

OUTPut?

queries the state of the main output and returns "0" (OFF) or "1" (ON).

Figure 3.6 Below shows how the Instrument control panel in WaveWiz

can be used to enable the main outputs. Checking the relevant box

will toggle each output on or off.

Selecting an

Output Type

There are three main types of waveforms that the model 301/302 can

produce: Standard (fixed), Arbitrary (user) and Sequenced waveforms.

Standard waveforms are computed from formulas that are built into

the program. The instrument can output arbitrary and sequenced

waveforms only after waveform data has been downloaded into its

memory.

Use the following command to select the output function type:

FUNCtion:MODE {FIXed | USER | SEQuence}

When “FIXed” is selected, the generator outputs the standard

waveform currently selected by the FUNC:SHAP command. When

“USER” is selected, the generator outputs the arbitrary waveform

currently selected by the TRAC:SEL command. When “SEQuence” is

selected, the generator outputs the sequence that is programmed

using the SEQ:DEF command. The query:

FUNCtion:MODE?

Queries the output function type and returns FIX, USER or SEQ.

Figure 3.6 Below shows how the Instrument control panel in WaveWiz

can be used select the waveform type..
