Step 6: Make Measurements
Things That Can Go Wrong
Measurement Integrity Always Returns a Value of 6
Background A measurement integrity value of 6 indicates that some characteristic of the input signal is
under range. Typically this will be the amplitude (power) of the DUT signal. This low amplitude will cause the
level of the DSP sampler to be below a threshold required by the measurement algorithm to produce results of
specified accuracy.
Possible Cause One of the most likely causes of a measurement underrange condition is DUT signal loss
caused by fixture loss or cable loss.
Suggested Workaround Fixture loss or cable loss can be compensated for by using the RF IN/OUT port’s
amplitude offset parameter.
Example 2. Command Syntax:
SYSTem:CORRection:GAIN <numeric value>[<suffix>]
SYSTem:CORRection:STATe <1|ON|0|OFF>
Complex form of command (sets gain to <numeric value> and state to ON using single command):
SYSTem:CORRection:SGAin <numeric value>[<suffix>]
Example 3. Programming Example:
OUTPUT Test_set;"SYST:CORR:SGA -6"
would set the RF IN/OUT port’s amplitude offset to
−
6 dB and set the correction state to ON.
