Performance Requirements
Calculated from Pulse Width and Period.
5% of reading + 3.0 ns + jitter error + offset error.
Add 0.5 ns if measurement is made between CH1 and CH2.
0.5 % of reading + 5% of start event transition time + 5% of
stop event transition time + 3.0 ns + jitter error + offset error.
Rise and Fall time measurement is made at 20% and 80%
points of transition and linearly extrapolated to the 10% and
90% points.
Accuracy is relative to time interval as measured on screen
using cursors. Measurement is made using peak-to-peak
transition for measurement points in percent.
Add 2%.
«= 5 ns.
< 10 Hz (with MINFREQ = 10 Hz).
Noise on the input signal causes jitter which introduces errors in
the measurements. The amount of jitter depends on the noise
amplitude and the slew rate of the input signals.
The amount of jitter can be calculated as:
jitter —
input noise
amplitude (peak)
input slew rate in div/sec
Input slew rate should be measured at 2 Volts/div.settings more
sensitive than the setting at the end of the measurements or at
5 mV/div, whichever is less sensitive.
The slew rate must be measured at the same points at which
the measurement will be taken. The points for the various
measurements are:
Measurement Points
