12 SCPI Command Reference
TRACe<1|2>:CPRI:EVM This command will read the plotfile data from the last EVM
measurement performed on the selected CPRI RX input and
return the results as text.
The data is written as a comma delimited list of I and Q
values. For example :
99, 286, -521, 288, 503, 507, 97, 116, etc.
The IQ data has been scaled by 1000 to minimize the
amount of data transferred. To plot an EVM constellation
from this data, note that the first data point is I, the second
data point is Q. Divide the values by 1000 and plot on an X-Y
scatter chart.
TRIGGER sub-system commands
Command Description
TRIGger:BNC:STATe ON|[OFF]|1|0 By default the BNC connectors on the rear
panel of the E6610A are disabled. This
command is used to enable them. All BNC
connectors are enabled or disabled
together using this command.
TRIGger:BNC:STATe? Queries the enable state of the BNC connectors. Res-
ult is either "BNC configuration disabled" or "BNC con-
figuration enabled".
TRIGger:SYNC:IN:STATe ON|OFF|1|0 Sets the state of the E6610A's SYNC-IN
BNC input to on or off.
Note: If the SYNC-IN state was switched
to on, then that BNC connector has been
enabled, and there is no need to use the
TRIGger:BNC:STATe command to enable
this input.
TRIGger:SYNC:IN:STATe? Queries the enable state of the SYNC-IN input. Result
is either "Sync in config disabled" or "Sync in config
enabled".
TRIGger:SYNC:OUT:STATe ON|OFF|1|0 Sets the state of the E6610A's SYNC-OUT
BNC output to on or off.
Note: If the SYNC-OUT state was
switched to on, then that BNC connector
has been enabled, and there is no need to
use the TRIGger:BNC:STATe command to
enable this input.
TRIGger:SYNC:OUT:STATe? Queries the enable state of the SYNC-OUT output.
Result is either "Sync out config disabled" or "Sync
out config enabled".
