To set the probe attenuation factor:
1
Press the channel key.
2
Press the
Probe
softkey until you have selected how you want to specify the
attenuation factor, choosing either
Ratio
or
Decibels
.
3
Turn the Entry knob
to set the attenuation factor for the connected probe.
When measuring voltage values, the attenuation factor can be set from 0.100:1 to
10000:1 in a 1-2-5 sequence.
When measuring current values with a current probe, the attenuation factor can
be set from 10.0 V/A to 0.0001 V/A.
When specifying the attenuation factor in decibels, you can select values from
-20 dB to 80 dB.
If Amps is chosen as the units and a manual attenuation factor is chosen, then the
units as well as the attenuation factor are displayed.
To specify the probe skew
When measuring time intervals in the nanoseconds (ns) range, small differences in
cable length can affect the measurement. Use
Skew
to remove cable-delay errors
between any two channels.
1
Probe the same point with both probes.
2
Press one of the probes associated channel key.
3
In the Channel menu, press
Probe
.
4
In the Channel Probe menu, press
Skew
; then, select the desired skew value.
Each analog channel can be adjusted ±100 ns for a total of 200 ns difference.
The skew setting is not affected by pressing
[Default Setup]
or
[Auto Scale]
.
