Triggering and Gating 5

INITiate[:IMMediate]

- places the counter in the wait-for-trigger state. In this state, trigger signals

are recognized and accepted. Readings taken after the counter is initiated by

INITiate[:IMMediate] are displayed and stored in the counter’s reading

memory (see Chapter 7 “Formats and Data Flow” for more information).

Initiating Example

//configure for frequency, set system trigger parameters

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

TRIG:SOUR EXT // trigger source external

TRIG:SLOP POS // external trigger slope - positive

TRIG:DEL 1 // 1s delay after trigger received

TRIG:COUN 2 // accept 2 system triggers

SAMP:COUN 100 // take 100 readings per system trigger

INIT // initiate the counter - wait for trigger state

FETc? // retrieve measurements from reading memory

READ?

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

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

neously read into the output buffer (see Chapter 7 “Formats and Data Flow”

for more information).
