How to Compensate for Internal
and External Delays
Precise measurements require exact timing. Generated signals must reach
the DUT simultaneously, response signals must be captured at the same
point of time by all analyzers.
The HP 81200 system supports timing adjustments at the
generator/analyzer connectors of the system, at the input and output
connectors of the DUT board or even at the pins of the DUT.
Figure 112 Supported Timing Adjustments
After installing new modules or after replacement of frontends a zero
adjust procedure has to be performed to synchronize the new outputs or
inputs with the ones already installed.
To compensate for signal delays in the used cables, a cable delay
compensation procedure can be performed.
To compensate for both, propagation delays on the DUT board and delays
in the cables, a cable and propagation delay compensation procedure can
be performed.
Delay compensation is done with the Deskew Editor.
