Performance Characteristics
Agilent 54640-series Performance Characteristics
Horizontal
Range 1 ns/div to 50 s/div
Resolution 2.5 ps
Vernier 1-2-5 increments when off, 25 minor increments between major settings when on
Reference Positions Left, Center, Right
Delay Range
Pre-trigger (negative delay)
Post-trigger (positive delay) Greater of 1 screen width or 1 ms
500 seconds
Analog Delta-t Accuracy
Same Channel*
Channel-to-Channel
±0.005% reading ±0.1% screen width ±20 ps
Example: for signal with pulse width of 10 us, scope set to 5 us/div (50 us screen width),
delta-t accuracy = ±{.005%(10 us) + 0.1% (50 us) + 20 ps} = 50.52 ns
±0.005% reading ±0.1% screen width ±40 ps
Digital Delta-t Accuracy
Same Channel
Channel-to-Channel
(non-Vernier settings)
±0.005% reading ±0.1% screen width ±(1 digital sample period, 1 ns)
Example: for signal with pulse width of 10 us, scope set to 5 us/div (50 us screen width),
and single pod active (1 GSa/s), delta-t accuracy = ±{.005%(10 us) + 0.1% (50 us) + 1 ns}
= 51.5 ns
±0.005% reading ±0.1% screen width ±(1 digital sample period) ±(chan-to-chan skew))
Delay Jitter 10 ppm
RMS Jitter 0.025% screen width + 30 ps
Modes Main, Delayed, Roll, XY
