RF Command Group
The Tektronix MDO4000/B Series Oscilloscope models, MDO4000C models with
option SA3 or SA6, and MDO3000 models have a built-in RF input, in addition to
analog and digital channels, which allows you to display, measure, performmath
on and analyze both time and frequency domain signals with one instrument.
The MDO4000/B and MDO4000C models with option SA3 or SA6 combine
the fun
ctionality of a mid-range oscilloscope and a standard spectrum analyzer,
which makes it able to provide several time-correlated display and measurement
options for RF traces.
The MDO3000 allows frequency domain measurements but does not offer
time-correlated display and measurement options for RF traces.
The RF commands are concentrated in the RF Command Group, but also appear
in other command groups, including Save and Recall, Waveform Transfer, Trigger
and Search. A table is available that links the RF features to their corresponding
commands, regardless of command group. (See page 1-2, New or Changed
Functionality Updates that Impact the Programmatic Command Set.)
Frequency Domain Trace
Types
The MDO4000/B/C and MDO3000 support four frequency waveform types:
The frequency domain window provides support for four spectrum traces, which
may be turned on and off independently.
1. RF Normal trace: Each acquisition is discarded as new data is acquired.
2. RF Max Hold trace: The maximum data values are accumulated over multiple
acquisitions of the RF Normal trace.
3. RF Min Hold trace: The minimum data values are accumulated over multiple
acquisitions of the RF Normal trace.
