3 53220A/53230A Measurements
resolution (all channels): 1.0E-15 * expected to 1.0E-5* expected
(default resolution corresponds to a 0.1s gate time)
- channel is counter channel 1, 2, or 3 specified as (@1), (@2), or (@3).
Period Measurement Examples
// using MEASure? - measure the period of a 100 ns (10 MHz)
// signal with 12-digit resolution
*RST // reset to start from known state
MEAS:PER? 100E-9, 1E-12, (@1)
----------------------------------------------------------
// using CONFigure - measure the period of a 100 ns (10 MHz)
// signal with 12-digit resolution
*RST // reset to start from known state
SYST:TIM 1.0 // 1s measurement timeout (per meas)
CONF:FREQ 100E-9, 1E-12, (@1)
SAMP:COUN 10 // take 10 readings

Notes
1. See Chapter 5 for information on triggering and number of readings per trig-
ger (sample count).
2. See Chapter 4 for additional information on counter threshold levels and on
configuring the input signal path.
