Product Overview
Being a high-performance active
logic probe, RPL1116 connects the
digital signals under test to the
MSO1000Z series digital
oscilloscope to realize the logic
analyzer function.
The 16 digital channels (D0-D15) of
RPL1116 are divided into two channel groups (D0-D7 and D8-D15) each of
which includes signal interfaces and ground interfaces. All the channels are
marked with different numbers on the label of the probe head to identify
different channels. RPL1116 provides 16 signal leads and 16 ground leads
to realize flexible connection of signals and reference ground. Users can
calibrate the probe zero by using the auto-calibration function in the LA
menu of the oscilloscope.

The Using Method of the Logic Probe
1．Connect RPL1116 to the oscilloscope: connect the active logic
head to the main cable input, and then connect the main cable output
to the digital signal input terminal at the front panel of the oscilloscope
as shown in the figure below.

2．Connect the signals under test to RPL1116: users can connect
any number (≤16) of the signals under test to RPL1116 according to
the test need. Note that the amplitude of the input signal should not
exceed the maximum working voltage range of the probe. RPL1116
provides two connection methods to realize convenient and flexible
detection.
Method one: users can connect the signals under test through
the probe leads separately. You can easily identify the
corresponding channel of each signal by the channel label on the
probe leads and the color information on the probe head as
shown in Figure 1.
Note: If crosstalk or ground bounce occurs during use, it might
be caused when channels share a single ground lead. So you are
recommended to add a ground wire to the signal lines of each
channel and twist them.
Method two: on the basis of method one, you can connect a
grabber to each lead and connect it to the device under test as

3．Set the probe: press LA at the front panel of the oscilloscope to
enter the probe setting menu. Users can view and set the following
parameters under this menu: threshold level (the threshold levels of
D0-D7 and D8-D15 can be adjusted independently), waveform size
(applicable to all the channels; wherein, item L is only available when
the number of active channels is no more than 8), channel label, probe
calibration and so on.
Note: When the probe is connected to the oscilloscope for the first
- 6 -
time or the temperature change is more than 5 degrees, you are
recommended to calibrate the probe zero using the auto-calibration
function in the LA menu and please disconnect all the connections to
the RPL1116 input terminal during the calibration.
4．Function Check: after finishing the above operations, the signal
under test will be displayed on the corresponding digital channel on
the oscilloscope screen. If no signal is displayed, please adjust the
oscilloscope to select proper general settings (such as the trigger
mode and timebase). If signal is still not displayed, please check the
electric connection and parameter settings again or please try to use
other probe (such as analog probe) to check the signal state of the
test point.
