Initiating example

//configure for frequency, set system trigger parameters

CONF:FREQ 5E6,0.1,(@2)

– equivalent to executing INITiate:IMMediate directly followed by FETCh?.

READ? example

//configure for frequency, set system trigger parameters

CONF:FREQ 5E6,0.1,(@2)

READ? //initiate the counter - fetch readings from memory

Once initiated, a valid trigger signal and a satisfied delay period (if specified)

moves the counter to the triggered state and the beginning of the gate cycle. The

counter remains in the triggered state until the sample count (readings per

trigger) is reached. The counter then returns to the wait-for-trigger state until the

next system trigger is received. The counter returns to the idle state once the

product of the trigger count x sample count is reached.

TRIG:SOUR EXT // trigger source external

TRIG:SLOP POS

// external trigger slope - positive

// 1s delay after trigger received

// accept 2 system triggers

SAMP:COUN 100

// take 100 readings per system trigger

// initiate the counter - wait for trigger state

// retrieve measurements from reading memory

With READ?, readings are displayed, stored in reading memory, and

instantaneously read into the output buffer (see

for more information).
