Agilent 33500 Series Waveform Generators Dual-Channel Operation Technical Overview The Agilent 33522A dual-channel waveform generator To use these features from the instrument's front panel, allows you to output waveforms on both channels indepen- press the channel output key above either channel's dently. This allows you to flexibly drive a device under test output connector. Then press More > Dual Channel on (DUT) in many common situations. However, some applica- the softkey menu. The menu shown in Figure 1 appears, tions require you to combine two signals on one channel; showing the current state of dual-channel features. for example, you may wish to add noise to a sine wave. Dual-channel operations are disabled in the factory Other applications may require signals that are related to default state. each other in some way. For example, you may wish to simulate two clock signals, where one clock's frequency is a multiple of the other's. The Agilent 33522A includes features for meeting these kinds of application challenges and more. You can use these features from the front panel softkey menus or via the Standard Commands for Programmable Instruments (SCPI) programming language. Figure 1. You can access the 33522A waveform generator's dual-channel settings via the softkey menu. The Dual Channel Operation menu allows you to adjust settings for frequency coupling, amplitude coupling, tracking and combing waveforms. Frequency Coupling [SOURce[1|2]:] Coupling enabled or FREQuency:COUPle[:STATe] disabled Frequency coupling allows you to specify that one channel's {ON|1|OFF|0} frequency must be related to the other channel's frequency [SOURce[1|2]:]FREQuency:COUPle:MODE Type of coupling used either by a ratio (multiplying) or an offset (adding). One {OFFSet|RATio} when STATe is ON common use of this would be to simulate a device with [SOURce[1|2]:] Frequency added when two clocks whose timing is related by a frequency ratio. FREQuency:COUPle:OFFSet MODE is RATio Frequency coupling is enabled by the first softkey in the [SOURce[1|2]:]FREQuency:COUPle:RATio Multiplier used when Dual Channel Operation menu.
