MEASure:RESistance?
MEASure:FRESistance?
[{<
range>|AUTO|MIN|MAX|DEF}
[,<
resolution>|MIN|MAX|DEF}],] (@<scan_list>)
Configure the specified channels for 2-wire or 4-wire measurements and
immediately sweep through the scan list one time. Note that this command
also redefines the scan list. The readings are sent directly to the output
buffer but the readings are not stored in reading memory.
For 4-wire measurements (FRES), the instrument automatically pairs
channel n with channel n+10 (34901A) or n+8 (34902A) to provide the
source and sense connections. For example, make the source connections
to the
HI and LO terminals on channel 2 and the sense connections to
the
HI and LO terminals on channel 12. Specify the paired channel in
the lower bank (source) as the scan_list channel.
MEASure:CURRent:DC?
MEASure:CURRent:AC?
[{<
range>|AUTO|MIN|MAX|DEF}
[,<
resolution>|MIN|MAX|DEF}],] (@<scan_list>)
Note: Current measurements are allowed only on channels 21 and 22
on the 34901A multiplexer module.
Configure the specified channels for dc or ac current measurements and
immediately sweep through the scan list one time. Note that this command
also redefines the scan list. The readings are sent directly to the
instrument’s output buffer but the readings are not stored in reading
memory. For ac measurements, the resolution is actually fixed at
6
1
⁄
2
digits; the resolution parameter only affects the number of digits
shown on the front-panel.
MEASure:FREQuency?
MEASure:PERiod?
[{<
range>|AUTO|MIN|MAX|DEF}
[,<
resolution>|MIN|MAX|DEF}],] (@<scan_list>)
Configure the specified channels for frequency or period measurements
and immediately sweep through the scan list one time. Note that this
command also redefines the scan list. The readings are sent directly to
the instrument’s output buffer but the readings are not stored
in reading memory. With no signal applied, “0” is returned.
