GNSS Positioning Simulator: What is the 1PPS signal rise time ?
Environment/Versions
GSS8000
GSS6700
GSS6300
GSS6300M
Measurement of the 1PPS signal rise time.
Answer
This is not a specified parameter within our product specification and not one that we usually measure.
For a GSS8000 type simulator this will typically average
1ns
for the 10%-90% points (see
Figure 1
for an example measurement).
For a GSS6300/6700 type simulators this will typically average about 5ns for the 10%-90% points (see
Figure 2
for an example measurement).
Note that this rise time can vary a little with load (e.g. cable length, termination impedance) but this will typically be a very small effect.
