The Arbitrary Source Option

Arbitrary Source Description

An arbitrary source can be included with the HP E1433A 8-Channel 196 kSa/sec Digitizer plus DSP as Option 1D4. (It cannot be installed with a Tachometer, Option AYF.) The Arbitrary Source Option can supply arbitrary or sine signals under control of measurement software.

Trigger

The Arbitrary Source can be used to trigger the measurement and to trigger other modules in the measurement system.

Arbitrary Output

The Arbitrary Source can be programmed to output any signal that is described by data downloaded by the software.

Source Output Modes

The Arbitrary Source has several output modes including the following:

￿arbitrary

￿sine

￿noise

￿random

￿burst

COLA (and Summer)

The COLA (Constant Output Level Amplifier) output supplies a signal similar to the Source “Out” output except that it is at a constant output level of about one volt peak.

The same connector (labeled “COLA”) can also be programmed as a summer input. A signal connected to this input is summed with the internal source output to create the final output.

External Shutdown

Shorting the center pin of the shutdown connector to its shield causes the source to ramp down and shut off.
