The first parameter returned by SSPARM? is the 
number of bursts that contained N samples. The 
second parameter is the number of bursts that 
contained N-1 samples. The third parameter 
returned is the value of N.
SSRC [source][,mode]
Sync Source. For sub-sampling (SSAC or SSDC 
command), the SSRC command synchronizes 
bursts to an external signal or to a voltage level 
on the input signal.
For synchronous ACV or ACDCV (SETACV SYNC 
command), the SSRC command synchronizes 
sampling to an external signal. You can also use 
the HOLD parameter to prevent the measurement 
method from changing to random should level 
triggering not occur within certain time limits. The 
time limits are determined by the AC bandwidth 
(ACBAND command) setting.
source = EXT (2), LEVEL (7)
Power-on source = LEVEL.
Default source = LEVEL.
mode = AUTO (1), HOLD (4)
Power-on mode = AUTO
Default mode = AUTO
SSTATE name
Store State. Stores the multimeter's present state 
and assigns it a name. States are recalled using 
the RSTATE command.
