HP E1433A User's Guide
Using the HP E1433A
Zoom (HP E1432A only)
Up to now the HP E1432A has made only baseband measurements (from zero to some frequency.) Zoom allows you to set a center frequency and look at a window of frequencies around it. It uses two new functions: hpe1432_setZoom (turns zoom on/off) and hpe1432_setCenterFreq. (Zoom has not been implemented for the HP E1433A).
Zoom (for the Arbitrary Source, option 1D4)
This is similar to zoom for the HP E1432A input. Zoom for the source allows you to set a center frequency and a span for the output signal. It uses the existing function hpe1432_setSourceMode with a new zoom parameter.
Zoom applies to random burst source mode and continuous source mode, for both the HP E1432A and the HP E1433A. When used with the
HP E1432A, if you set the source center frequency to zero, the source center frequency will be the same as the center frequency set for the HP E1432A input. This is also true for the span.
