Technical data

The command sets the DUT relax time. This is the time that takes effect after the
measured BER is higher than the target BER. The next BER measurement starts
after this time has elapsed. The unit is seconds.
The query returns the present value in seconds.
MEAS:JTOL:CHAR(*):FETC:DATA:AVAilable?
IAgilentN490xJCharacterizationMeasurement.GetDataCount()
MEAS:JTOLerance:CHAR(*):FETC:DATA:AVAilable?
This query returns the number of measured points in integer format (NR1). The
number is continually updated until the measurement has finished.
MEAS:JTOL:CHAR(*):FETC:DATA:POINts?
IAgilentN490xJCharacterizationMeasurement.GetDataPoints()
MEAS:JTOLerance:CHAR(*):FETC:DATA:POINts? <NR1>,<NR1>
This query returns the results of measured points.
The first parameter specifies the number of points (must be between 1 and the
number of measured points, as returned by MEAS:JTOL:CHAR
(*):FETC:DATA:AVAilable?), the second parameter specifies the start point (0 is the
highest point at the start frequency).
For example, if the number of measured points is 119, you can request
• all points: MEAS:JTOL:CHAR(*):FETC:DATA:POIN? 119,0
• a single point: MEAS:JTOL:CHAR(*):FETC:DATA:POIN? 1,42
• the first 12 points: MEAS:JTOL:CHAR(*):FETC:DATA:POIN? 12,0
• 40 points in the middle: MEAS:JTOL:CHAR(*):FETC:DATA:POIN? 40,40
The results for each point are returned as a comma-separated list with the following
contents:
• Frequency in Hz (NR3)
• Jitter amplitude in UI (NR3)
• the measured BER (NR3)
• the number of received bits (NR3)
