RF Output Power Problems
Check the
RF ON/OFF
annunciator on the display. If it reads
RF OFF
, press
RF On/Off
to toggle the RF
output on.
No RF Output Power when Playing a Waveform File (E8267D only)
Preset the signal generator, then replay the waveform file.
If a header file is not specified for a waveform, the signal generator uses a default header file with
unspecified settings. If you play a waveform file that has unspecified signal generator settings;
(settings not saved to the file header, see
page 94 ), the signal generator will use the header file
settings from the previously played file. If the previous header file had a marker routed to RF
blanking, the RF output power will be blanked. Preset the signal generator to return the RF blanking
marker function to its default state (Off)). Refer to the
Key Reference , Marker section, for more
information.
NOTE If the default marker file is used, ensure that the
Pulse/RF Blank
softkey is set to
None
. Markers
may have been set to
Pulse/RF Blank
by a previous file header.
