Command Syntax
:ECONtour{1:16}:RNSValue:LEVel{0:3} <random_noise>
Where the required specifier {1:16}
identifies a group of contour lines.
Where <random_noise> is a double.
Query Syntax
:ECONtour{1:16}:RNSValue:LEVel?
Description
For Random Noise (RN) stabilization, sets the value of RN for the selected eye level of an eye-contour group. PAM4 signals have four possible levels: 0, 1, 2, and 3. NRZ signals has two possible levels: 0 and 1. There are actually four commands, one for each eye level on the signal.
- :ECONtour{1:16}:RNSValue:LEVel3 (for PAM4 only)
- :ECONtour{1:16}:RNSValue:LEVel2 (for PAM4 only)
- :ECONtour{1:16}:RNSValue:LEVel1 (for NRZ and PAM4)
- :ECONtour{1:16}:RNSValue:LEVel0 (for NRZ and PAM4)
To measure the RN, switch the N1000A to Jitter Mode and measure the RN while using a signal that has a short pattern. Or, measure the RN using a separate instrument. Use the :ECONtour:RNSTabilize
command to turn on or off the use of RN stabilization.
