Syntax
CONFigure:FREQuency[<range|MIN|MAX|DEF>
[,<resolution|MIN|MAX|DEF>]]
This command presets and configures the U2741A for frequency measurements
with the specified range and resolution. This command does not initiate the
measurement.
Parameters
Remarks
– The
CONF
command does not place the U2741A in the “wait-for-trigger” state.
Use the
INIT
or
READ?
command in conjunction with
CONF
to place the
U2741A in the “wait-for-trigger” state.
– Frequency is measured on AC voltage signals. Thus, the proper AC voltage
should be first set using the
[SENS:]VOLT:AC:RANG
command. The voltage
range should be 0.1 V or greater for more accurate frequency measurement.
– The range parameter is required only to specify the measurement resolution
parameter. Therefore, it is not necessary to send a new command for each new
frequency to be measured.
– If the input signal voltage is greater than can be measured on the selected
voltage range (manual range), the U2741A gives an overload indication of
+9.9E+37
from the remote interface. Autorange can be enabled for the input
voltage.
– The frequency measurement does not autorange.
– With no signal applied,
0
is returned.
