Simple measurement procedure (MEASure)
For simple measurement procedures, use MEASure:<meter_fn>?. Refer to Table 5 and replace <meter_fn> with the required measurement function. When this query is used, the measurement condition setup are set to default values, which allows the measured data to be retrieved with minimum effort.
|'Start the impedance measurement and query the data (magnitude of the impedance).|
|MEAS:VOLT?||'Start the voltage measurement and query the data.|
|MEAS:CURR?||'Start the current measurement and query the data.|
|MEAS?||'This query cannot be used. (You must explicitly specify <meter_fn>.)|
There are more detailed variations of MEAS:IMP such as MAGN (magnitude), RES (resistance), REAC (reactance), PHAS (phase angle), VOLT:CYCL (voltage measurement (Voltage synchronized to the impedance measurement)), and CURR:CYCL (current measurement (Current synchronized to the impedance measurement)). [MAGN] can be omitted. Thus, MEAS:IMP? and MEAS:IMP:MAGN? are equivalent. In the impedance measurement, RESistance, REACtance, PHASe, VOLTage:CYCLe, and CURRent:CYCLe are measured simultaneously in addition to MAGNitude. In the example below, MEAS:IMP? is used to measure the magnitude of the impedance and FETCh? is used to retrieve the resistance, reactance, and phase values that are measured simultaneously during the impedance measurement. An example of using FETCh? is given later.
MEAS:<meter_fn>? allows you to easily make measurements even if you do not have a detailed knowledge of the KFM2150. The down side is that a portion of the settings related to the measurement functions is set to default. This prohibits you from setting detailed measurement conditions. To make measurements with detailed setup conditions, use READ[:<meter_fn>]?.
