MEAS?
Triggers (or in continuous trigger, retriggers) a new measurement, waits for it to
complete, then returns the value of the present input measurement (the most
recently completed input measurement). If a timeout argument is given and no
settled measurement occurs within the specified timeout period, the command
generates an error and presents the closest approximation of the measurement
obtained in the period. The MEAS? command is equivalent to the following
sequence of commands: TRIG; *WAI; VAL?
Parameter
\<timeout in seconds\> (optional)
Response
1. (Float) The magnitude of the measurement in volts.
2. (Float) The frequency of the measurement in Hertz.
3. (Integer) A code describing the measurement as follows. If more than one
condition is true, only the highest number is returned.
• 0 = Measurement conditions valid, no other condition below is true
• 1 = Frequency underrange
• 2 = Frequency overrange
• 3 = Measurement settled, but digital filter not full
• 4 = Measurement is unsettled ("U" annunciator is lit)
• 5 = Value is underrange ("Under Range" on display)
• 6 = Value is overrange ("Over Range" on display)
• 7 = Value is invalid ("--------" on display)
