To Set the ARB Reference

Custom Arb Waveform Generator

Configuring Hardware

9.Press Ext Delay Time > 100 > msec.

The Custom Arb Waveform Generator has been configured to play a single multicarrier waveform 100 milliseconds after it detects a change in TTL state from low to high at the PATT TRIG IN rear panel connector.

10.Set the function generator waveform to a 0.1 Hz square wave at an output level of 0 to 5V.

11. On the signal generator, press Mode > Custom > Arb Waveform Generator > Digital Modulation Off On until On is highlighted.

This generates a waveform with the custom multicarrier state and the display changes to Dig Mod Setup: Multicarrier.

During waveform generation, the DIGMOD and I/Q annunciators activate and the new custom multicarrier state is stored in volatile ARB memory. The waveform should be modulating the RF carrier.

12.Press RF On/Off.

The externally single- triggered custom multicarrier waveform should be available at the signal generator’s RF OUTPUT connector 100 ms after receiving a change in TTL state from low to high at the PATT TRIG IN.

Setting for an External or Internal Reference

1.Press Custom > Arb Waveform Generator > More (1 of 2).

2.Press ARB Reference Ext Int to select either external or internal as the waveform sample clock reference.

•If you select Ext, you must enter the reference frequency (250 kHz to 100 MHz) and apply the reference signal to the rear- panel BASEBAND GEN REF IN.

•If you select Int, the internal clock is used for the arbitrary waveform (ARB) frequency reference.

Setting the External Frequency

The external Arb reference frequency is only used when the ARB Reference Ext Int softkey has been set to Ext (external).

1.Press Custom > Arb Waveform Generator > More (1 of 2).

2.Press Reference Freq, enter a desired frequency (250 kHz to 100 MHz), and press MHz, kHz, or Hz.
