Input-output port specifications
Auxiliary trigger input
characteristics and range
≥4 GHz models 50 Ω, ±4 V (DC plus peak AC)
MSO/DPO70000DX: 50 Ω, ±5 V (DC plus peak AC)
<4 GHz models 50 Ω, ± 5%; maximum input voltage ± 5 V (DC + peak AC)
1 MΩ, ±5%, 150 V CAT1. Derate at 20 dB/decade to 9 V RMS above 200 kHz
Auxiliary output logic polarity and
functionality
Default output is A trigger low true (a negative edge when the A trigger event occurs). You can also
program the output to A trigger high true, B trigger low or high true, disabled, force high, and force
low.
Auxiliary output logic levels
V
out
high V
out
low (true)
≥2.5 V into 1 MΩ load,
≥1.0 V into 50 Ω load to ground
≤0.7 V into 1 MΩ load
≤0.25 V into 50 Ω load to ground
CH3 output voltage typical < 4 GHz
models
50 mV/div ± 20% into a 1 MΩ load
25 mV/div ±20% into a 50 Ω load
High speed serial data output baud
rate range
≥ 4 GHz models Fbaud ≤ 1250 MB. Output swing of 1010 repeating pattern at this baud will be at least 200 mV into
50 Ω.
High speed serial clock output
frequency range
≥4 GHz models Peak-to-peak output swing at 625 MHz is at least 200 mV p-p into 50 Ω. Higher frequencies are
further attenuated by approximately 6 dB per octave above 625 MHz.
Use AC or DC coupled 50 Ω termination; AC coupling the clock provides about 10% more
amplitude.
High speed serial data and clock
output voltages, typical
≥4 GHz models Voh = -1.0 V
Vol = -1.7 V
Assumes a load impedance greater than 1 kΩ. (50 Ω source termination.)
If a 50 Ω or 75 Ω load is used, either use a DC blocking capacitor in series with the signal or
reference the termination to about -1.3 V. The signal amplitude will be correspondingly reduced.
