Measurement Using a Single Measurement Function

The simplest measurement procedure (MEASure)

The simplest measurement procedure is to use the MEASure:<meter_fn>? query.

When this query is used, all measurement conditions excluding the range setting are set to default values, which allows the measured data to be retrieved with minimum effort.

The FUNC:CONC OFF command must be sent in advance so that multiple <meter_fn>s are not selected concurrently. The default setting immediately after the KFM2005/KFM2030 is turned on and the default setting for the *RST and *RCL commands is FUNC:CONC ON. Therefore, multiple <meter_fn>s are selected concurrently.

Example:Example:

FUNC:CONC OFF   'Prohibit the selection of multiple <meter_fn>s.

MEAS:IMP?

  'Start the impedance measurement and query the data.
MEAS:VOLT? 'Start the voltage measurement and query the data.
MEAS:CURR? 'Start the current measurement and query the data.

 

MEAS? query cannot be used (<meter_fn> must be specified explicitly).

There are more detailed variations of MEAS:IMP such as MEAS:IMP[:MAGN]?, MEAS:IMP:RES, MEAS:IMP:REAC?, and MEAS:IMP:PHAS?.

They measure the MAGNitude, RESistance, REACtance, and PHASe in the impedance measurement, respectively. [MAGNitude] can be omitted. Thus, MEAS:IMP? and MEAS:IMP:MAGN? are equivalent. In the impedance measurement, RESistance, REACtance, and PHASe are measured simultaneously in addition to MAGNitude. In the example below, the MEAS:IMP? query is used to measure the absolute value of the impedance and the FETC? query is used to retrieve the resistance, reactance, and phase values that are measured simultaneously during the impedance measurement. An example of using the FETC? query is given later.

MEAS:IMP?

FETC:IMP:RES?

FETC:IMP:REAC?

FETC:IMP:PHAS?

Because the MEAS:<meter_fn>? query calls the CONF:<meter_fn> command internally, the measurement conditions of the KFM2005/KFM2030 are set as shown in Table.

The MEAS:<meter_fn>? query allows you to easily make measurements even if you do not have a detailed knowledge of the KFM2005/KFM2030. The down side is that all settings related to the measurement functions are set to default. This query is inflexible and does not allow you to set detailed measurement conditions. To make measurements using setup conditions with a little more detail, use the CONF:<meter_fn> command and READ[:<meter_fn>]? query. ->Measurement procedure with a little more flexibility (CONFigure and READ)

The MEAS:<meter_fn>? query is equivalent to the combination of the CONF:<meter_fn> command and READ[:<meter_fn>]? query.
