RWS_n?<br />
Read Single Channel Measurement With Status Query<br />
Syntax: RWS_n?<br />
Parameters: None<br />
Function:<br />
This query returns the last measurement taken from the specified channel.<br />
The units of this measurement are the units defined at the time the reading<br />
was made. Because it is possible to make this query faster than measurements<br />
are actually being taken, the values returned by successive queries<br />
may be multiple reports of the same measurement.<br />
To ensure that fresh data is being read the NDA(new data available) bit in the<br />
Status Byte can be checked either by issuing a serial poll or by using the<br />
*STB? command. A serial poll is recommended if the GPIB interface is being<br />
used. The NDA bit will be 1 if the last measurement has not been read. The<br />
NDA bit for the specified channel will be reset to 0 immediately after a measurement<br />
is queried from that channel and will stay 0 until a new reading is<br />
taken.<br />
Returns: ,<br />
is an integer that represents the status of the returned value.<br />
will be 0 for ok, 1 for over range, 2 for saturated and 3 for data error,<br />
and 4 for ranging.<br />
is a floating point number in the exponential format.<br />

SFREQ<br />
DC Sample Frequency Select<br />
Syntax: SFREQ <br />
Parameters:<br />
The parameter is of type . The range of this number depends<br />
on the current DC sample precision (see SPREC). If the precision is<br />
20000 then the range is 0.001 to 25Hz. If the precision is 4096 then the range is<br />
0.001 to 500Hz when two detector calibration modules are plugged into the<br />
meter and 1000Hz for one.<br />
Function:<br />
This command determines how often a signal is sampled when in DC continuous<br />
mode. Both channels sample data at the same rate when in DC continuous<br />
mode.<br />
