Measurements
signal measurements
fundamental frequency,
total harmonic distortion relative to
fundamental (THD
F
) or relative to
RMS amplitude (THD
R
)
harmonic measurements
RMS amplitude and amplitude relative to
amplitude of the fundamental,
phase angle relative to the fundamental
and frequency

RTH-K38
User scripting
Enables to run user scripts on the R&S
®
RTH1002 and R&S
®
RTH1004.
The script allows to control the instrument via SCPI commands and access all parameters. The option also supports to display
measurement results on the instrument in an individual screen area.
Supported script languages: Html, Javascript
The R&S
®
RTH-K38 option requires an external computer to program the script and copy it onto the instrument. Once the script has
been loaded into the R&S
®
RTH1002/R&S
®
RTH1004, it can be started from the instrument without any PC connected.
