(5) Burst data setting
Set the Burst data. The Burst data includes Gap Length and Frame
Length, and they should be set respectively. For a non-Burst
continuous wave, set the number of samples per frame of the used
communication system or “1” for Frame Length, and set “0” for Gap
Length. When an external trigger is used, the waveform pattern
output timing is determined based on this setting. For details on
external trigger, refer to 3.5.4 “Outputting signal in sync with
external trigger signal” in
MG3700A Vector Signal Generator
Operation Manual (Mainframe)
, or 7.4.1 “Route Input Connectors”
in
MG3710A/MG3710E/MG3740A Operation Manual (Mainframe)
.
(6) RF Gate setting
Configures the RF gate settings. These parameters are enabled only
when the file format is set to ASCII1, ASCII2, ASCII3, or MS269x/
MS2830A/MS2840A Digitizer. When the RF Gate checkbox is
selected, RF Gate processing is performed during waveform pattern
conversion for samples in which the I and Q values (
jQ
I
+
) of the
input ASCII file or digitized file data are continuously at or below
the threshold level. The threshold level can be set by entering the
ratio to the waveform pattern peak value in the RF On/Off
Threshold text box. The RF Gate is executed only for the samples in
which the I and Q values less than the threshold level continue for
longer than the value set in the Minimum RF Gate Length text box.
Since the samples for which the RF Gate is executed are excluded
for rms calculation during waveform pattern conversion, it is
therefore possible to prevent underestimation of the rms value of the
burst signal waveform pattern (accordingly, the output level in a
burst-on interval can be kept under the specified RF output level)
(7) Data conversion
Starts file conversion.
(8) Exit
Ends the conversion process.
