J1 Input – Time Interval - Event Time

The Time Interval - Event Time (TIET) option measures a 1 PPS or Event input signal on J1 against the XLi derived time. The rising edge of the pulse is measured against XLi time with 5 ns resolution.

Pulse Width	100 ns, min.
Active Edge:	Rising
Amplitude (DC):
Logic Low:	< 1.25V and Min. 300mV
Logic Hi:	>1.25V and Max 10V
Impedance:	100 kΩ, 50 Ω
Resolution:	5 ns, Single Shot
Accuracy	Refer to “System Time & Frequency Accuracy” on page 10

See “F110 – J1 Input (TIET)” on page 99.

Note: Any stray input capacitance loading will impact TIET measurements

Note: Configuring J1 as the input for a time code reference source is not supported.

J2 Output – Rate Out

Rate:	1 PPS, 10 PPS, 100 PPS, 1 kPPS, 10 kPPS, 100 kPPS, 1 MPPS, 5
	MPPS, 10 MPPS
Duty cycle:	40-60% ± 10%
Amplitude (TTL):	TTL Levels into 50 Ω
Quantity:	1
Connector:	Female BNC
Factory setting:	10 MPPS

See “F111 – J2 Output (Rate)” on page 102.

Note: Configuring J2 as a Programmable Pulse Output (PPO) is not supported.
