Hi
I own a PCSU1000, and would like know what the tolerances are for the PCSU1000. Specifically I need to the following:
accuracy of the A to D converters (vertical accuracy and resolution),
sensitivity of the scope (minimum voltage which the instrument can sense through maximum input voltage - not listed below),
Time Base Accuracy (horizontal accuracy).
For instance Tektronix gives the following tolerance specifications for their TDS1001B:
Vertical Resolution: 8 bits
DC Vertical Accuracy: +3% on all models
Time Base Accuracy: 50 ppm
So for the sample rage of 1GS/s this is ± how much, or how many ppm does the PCSU1000 have?

These are the values for the PCSU1000:
Vertical Resolution: 8 bits
AC Vertical Accuracy: 2% typical
Time Base Accuracy: 100 ppm
Input sensitivity: 0.15mV display resolution

The AC gain of all the units is adjusted in production.
AC Vertical Accuracy is typically better than 2%
The input sensitivity is calculated following way:
On the most sensitive range the peak-to-peak display is 40mV. The 8 bit conversion can output 256 different value steps. Each step is about 0.15mV.
