Other Outputs

The Other Outputs tab is accessed from the Configure In/Out control panel (Setup > Configure In/Out).
The IQ output settings appear only when Option 55 is installed.
IQ Output
The Digital IQ Output transmits the digitized analyzer data for capture and storage by external equipment.
The I/Q data is provided in 16-bit, two's complement format, along with clock and data-valid signals.
There are three selections available for the IQ Output: Off, On, and Test. When in the "Off" position, the
IQ Output is disabled, and all lines are static. When in the "On" position, the data is output as described in
the SPECMON3 Real-Time Spectrum Analyzer and SPECMON6 Series Real-Time Spectrum Analyzer
Specifications and Performance Verification Technical Reference (Tektronix part number 077-0742-XX).
Use the "Test" position to verify operation when setting up your equipment. When in the "Test (Counting
Pattern)" position, the I channel data will be counting up and the Q channel data will be counting down.
The EXT_IQ_CLK and EXT_IQ_DAV signals will operate at a rate consistent with the instrument SPAN
setting.

Mapping Measurements

The SPECMON3 and SPECMON6 can record measurements on a map using the included RSA Map
software. The RSA Map software lets you record measurements on a geo-referenced map or a bitmap map
for documentation purposes. If an external GPS receiver is connected to the analyzer, measurements can
be mapped at the GPS coordinates where the measurement was taken. Using an external GPS receiver,
RSA Map can perform repeat measurements using either time or distance to initiate measurements.
RSA Map software can also save results for future reference or analysis.
To map measurements:
Select Tools > RSA Map. This launches the RSA Map software in a separate window.
