Specifications
Input Frequency:
DC, 1 H z - 300 MHz,
100 Hz - 300 MHz default
(higher LF limit means higher
meas. speed)
Mode:
V max, V min, V p-p*
Resolution:
1 (10) mV
*Accuracy (typ.):
DC
1% ± 15 (150) mV
1 H z - 1 k H z
1% ± 15 (150) mV
1 kHz - 20 MHz
3% ± 15 (150) mV
20 - 100 MHz
10% ± 15 (150) mV
100 - 300 MHz

* V p-p is calculated as Vmax - V min,which means
that the maximum absolute error will be ±30
(300) mV.

*Main Parameters:
A, B
*Calc. Parameters:
A+B, A-B, A/B
Modes:
Manual, Gated,
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 pac-
ing 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 pos-
itive 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:
50 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 measure-
ments, 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 trig
