Measurement using the concurrent measurement function
Using multiple measurement functions
The KFM2005/KFM2030 can use all these measurement functions concurrently. This is the concurrent measurement function. Immediately after the KFM2005/KFM2030 is turned on or after the *RST or *RCL command is used, the concurrent measurement function is on, and the impedance, voltage, and current measurement functions are selected simultaneously. To explicitly turn off the concurrent function, use the FUNC:CONC OFF command.
FUNC:CONC OFF
This command turns the concurrent function off, and selects IMP alone as the <meter_fn>.
FUNC:CONC ON
This command turns the concurrent function on, but it does not affect the current selection status of <meter_fn> (whether single or multiple meters are selected).
FUNC:ALL
This command selects all <meter_fn>s simultaneously. This is equivalent to the following commands.
FUNC:CONC ON
FUNC "IMP","VOLT","CURR"
If all <meter_fn>s, IMP, VOLT[:DC], and CURR[:DC], are selected simultaneously, the MEAS:<meter_fn>? query or the READ[:<meter_fn>]? query can be used. However, these queries cannot start other measurement actions until one measurement action is completed. In other words, these queries do not allow simultaneous measurement of different <meter_fn>s. (The exceptions are VOLT and CURR. These are always measured simultaneously, because they are part of the same sequence 2 group.)
To start all measurement actions simultaneously, use the INIT command. Because the INIT command is an abbreviation for INIT[:IMM][:ALL], the command starts measurements of all selected <meter_fn>s simultaneously.
Example: Configures all <meter_fn>s, and starts the measuremen
