Start/Stop or Timed
* If A or B is the main parameter, A-B and
A/B will be displayed as aux. parameters.
If one of the calculated parameters is the main
parameter, A and B will be displayed as aux.
parameters.
NOTE: MANUAL controlled by front panel push
button HOLD/RUN. Statistics and
pacing inhibited.
GATED, START/STOP and TIMED
controlled by setting arming conditions
on the free input channels. Statistics
and pacing allowed.
Timestamping A, B
This function is only accessible via GPIB or
USB.
No absolute time exists; timestamp values
can only be used for relative time
measurements.
Timestamps are taken of two consecutive
positive edges and two consecutive negative
edges (pos, neg, pos, neg or neg, pos, neg,
pos) and the number of positive edges is
counted.
Max. Frequency:
160 MHz
Min. Pulse Width:
2.5 ns
Timestamp Reso-
lution:
35 ps rms
Max. Frequency to
catch each edge:
250 kHz
Auto Set / Manual Set
All measuring functions can be auto-set
using best settings for the individual
functions. This means e.g. an auto hysteresis
of 33% of Vp-p in frequency measurements,
an auto trigger at 50 % of Vp
-
p with
minimum hysteresis incl. hysteresis
compensation in time measurements, an auto
find of burst length and auto sync for
frequency burst measurements, etc.
NOTE: The frequency range for inputs A &
B, is up to 300 MHz for Auto trig, and up to
400 MHz for Manual tri
