Optimizing Measurement Results
Reducing Receiver Crosstalk
Reducing Receiver Crosstalk To reduce receiver crosstalk you can do the following:
• Perform a response and isolation measurement calibration.
• Set the sweep to the alternate mode.
Alternate sweep is intended for measuring wide dynamic range devices, such as high pass
and bandpass filters. This sweep mode removes a type of leakage term through the device
under test, from one channel to another.
To set the alternate sweep, press .
Refer to "Frequency Response and Isolation Error Corrections" on page 6-17.
Reducing Recall Time To reduce time during recall and frequency changes, the raw offset function can be turned
off. To turn this function off, press .
The raw offset function is normally on and controls the sampler and attenuator offsets.
The creation of this table takes some time during a recall of an instrument state.
Raw offsets may be turned on or off individually for each channel. They follow the channel
coupling. For dual channel operation, raw offsets should be turned off for each channel if
the channels are uncoupled.
Refer to “Specifications and Characteristics” chapter i n the reference guide for examples of
recall state times with the following functions on or off: raw offsets and blank display.
Using blank display may speed up recall times.
