To Perform A Conversion Loss Calibration - HP 8711C User Manual

深圳市盛腾仪器仪表有限公司
Conversion loss measurements typically utilize only a normalization
calibration. See "To Perform a Normalization Calibration" earlier in this
chapter.
When in conversion loss measurement mode, the analyzer is using its internal
broadband detectors and pressing the (CAL) key calls up a menu for zeroing
the detectors. Zeroing the detectors helps compensate for drift due to changes
in ambient temperature. The two m selections for conversion loss mode
are:
temperature. When autozero is selected, the detectors are automatically
zeroed approximately every five minutes. A pop-up message will briefly
appear on the analyzer's display when the detectors are zeroed.
In manual zero mode, the analyzer zeros the detectors only when the
Zero softkey is pressed.
N O T E
When zeroing the detectors, the analyzer turns off the internal RF source. If you are measuring an
external source with the broadband detectors, use Manual Zerr, bei'ke the external source is
connected to the TRANSMISSION port.
