(assume edge shape that results from Gaussian filter response)

The formula to calculate delta-time measurement accuracy (DTA) for a given instrument setting and input signal assumes

insignificant signal content above Nyquist frequency, where:

SR 1 = Slew Rate (1st Edge) around 1st point in measurement

SR 2 = Slew Rate (2nd Edge) around 2nd point in measurement

N = input-referred guaranteed noise limit (VRMS)

TBA = timebase accuracy or Reference Frequency Error

t p = delta-time measurement duration (sec)

Aperture uncertainty

≤ 0.450 ps + (10-11 * Measurement Duration)RMS, for measurements having duration ≤ 100 ms

Delay between analog channels,

full bandwidth, typical

≤ 100 ps for any two channels with input impedance set to 50 Ω, DC coupling with equal Volts/div or above 10 mV/div

Delay between analog and digital

FlexChannels, typical

3 ns when using a TLP058 and a passive probe matching the bandwidth of the scope, with no bandwidth limits applied

Delay between any two digital

FlexChannels, typical

3 ns from bit 0 of a FlexChannel to bit 0 of any other FlexChannel

Delay between any two bits of a

digital FlexChannel, typical

160 ps

Trigger system

Trigger modes

Auto, Normal, and Single

Trigger coupling

DC, HF Reject (attenuates > 50 kHz), LF Reject (attenuates < 50 kHz), noise reject (reduces sensitivity)

Trigger holdoff range

0 ns to 20 seconds

Trigger jitter, typical

≤ 7 psRMS for sample mode and edge-type trigger
