around the oscilloscope’s BNC connector. Therefore, the
oscilloscope will automatically set the attenuation factor for
recognized Agilent passive probes.
Passive probes that do not have a pin that connects to the ring
around the BNC connector will not be recognized by the
oscilloscope, and you must set the probe attenuation factor
manually.
Active Probes
All 6000 Series oscilloscopes except the 100 MHz bandwidth
models (MSO/DSO6012A and MSO/DSO6014A/L) have an
AutoProbe interface. Most Agilent active probes are compatible
with the AutoProbe interface. The AutoProbe interface uses a
series of contacts directly below the channel’s BNC connector to
transfer information between the oscilloscope and the probe.
When you connect a compatible probe to the oscilloscope, the
AutoProbe interface determines the type of probe and sets the
oscilloscope’s parameters (units, offset, attenuation, coupling,
and impedance) accordingly.
Manually Setting the Probe Attenuation Factor
If you connect a probe that the oscilloscope does not
automatically identify, you can set the attenuation factor as
follows:
1Press the channel key
2Press the Probe softkey
3Turn the Entry knob to set the attenuation factor for the
connected probe.
The attenuation factor can be set from 0.1:1 to 1000:1 in a 1-2-5
sequence for measuring voltage. The attenuation factor can be
set from 10 V/A to .001V/A to for measuring current values with
a current probe. The probe attenuation factor must be set
properly for measurements to be made correctly.
