Oscilloscope probes
The two oscilloscope probes supplied with the logic analyzer are
HP 1160A Miniature Passive Probes. These small, lightweight probes
allow measurements that were previously very difficult in densely
populated circuits.
For complete information on the operation, maintenance, and
adjustments of the miniature passive probes, be sure to read the
operating note that is packaged with the probes.
Probe Inputs
Probe inputs are located on the front panel to the right of the power
switch. Input 1 is on the left. The probes may be connected directly to
the BNC input connectors. The signal is dc-coupled to the oscilloscope.
BNC cables can be connected directly to the BNC connectors. A BNC-
to BNC cable is not provided with the instrument, but you can order it
separately.
Maximum Probe Input Voltage
The maximum input voltage of each logic analyzer probe is ±40 volts
peak. The maximum input voltage of the oscilloscope is ±250 volts dc
at 1 M
Ω
setting and 5 volts rms at 50
Ω
setting.
Calibration Outputs
There is one calibration output BNC located on the rear panel. It is the
AC/DC calibration signal source. This signal is used during calibration
of the oscilloscope. This calibration signal can also be used for probe
compensation adjustment.
