Measurement procedure with flexibility (READ)

The measurement procedure using the CONF:VOLT command and READ? query separates the measurement condition setup from the measurement start and data acquisition procedures. This enables you to specify detailed conditions between the setup and measurement start procedures. For the default settings set by the CONF:VOLT command, see Table 13.
You can set the settings to default using the CONF:VOLT command, specify other settings, and then start the measurement using the READ? query.

Example: |  |
CHAN:VOLT:NSEL 1 |  | 'Select logical channel 1.
CONF:VOLT |  | 'Set voltage scanning to default.
VOLT:RANG 20V |  | 'Set the selected channel to 20 V range.
VOLT:PROT 16;LOW 2 |  | 'Start the measurement and query the measured data.Set the selected channel to OVP 16 V and UVP 2 V.
READ? |  | 'Start voltage scanning on all activated channels, and query the measured data.

To abort the measurement after it is started, use the ABORt command. You can also use the *RST command or break signal to abort the measurement. The *CLS command does not abort the measurement. Once the measurement starts, you cannot enter settings related to the test conditions. You can specify the settings again after the test is completed or aborted.

The measurement procedure using the CONF:VOLT command and READ? query is flexible in that the measurement conditions can be specified in detail. However, because the READ? query itself contains the function of the measurement start command, it is still inflexible in terms of specifying the measurement timing. This is because, measurement is started every time the READ? query is issued. To program the measurement timing in detail, the measurement start and data acquisition procedures must be separated. The commands that allows you to do this are INIT and FETC?. The READ? query is equivalent to combining the INIT command and FETCh? query.
