产品简介
RPL1116 是一款高性能有源
逻辑探头，可将待测系统上
的数字信号连接至 RIGOL
MSO1000Z 系列数字示波
器，实现逻辑分析仪功能。
RPL1116 共有 16 个数字通道
（D0-D15），分为两个通道组
（D0-D7 和D8-D15）。 每个数
字通道组包含信号接口和地
接口。同时，RPL1116 标配 20
根信号引线以及 20 个探头钩，可用于灵活的连接被测信号和参考地。利用示
波器 LA 菜单中的自校准功能可以校准探头的零点。

逻辑探头的使用方法
1．连接 RPL1116 至示波器：将RPL1116 前端连接至主线输入端，然后
将主线输出端连接至示波器前面板的数字信号输入端，如下图所示。
2．连接被测信号至 RPL1116：用户可以根据测试需要将任意数量（≤16）
的被测信号连接至 RPL1116。连接时需要注意，输入信号的幅度不能超
过探头的最大工作电压范围。RPL1116 提供了两种连接方式方便用户灵
活探测信号。

- 4 -
方法一：用户可通过前端引线单独连接各个被测信号。通过前端引
线上的通道标示以及探头前端上的颜色信息可方便地识别每个信
号所对应的通道号，如图 1所示。
注意：使用过程中若出现串扰或地弹，可能是多通道共用地线导致。
因此建议您尽可能为每通道的信号线配一根地线并双绞。
方法二：在方法一的基础上，可为前端引线连接上探头测试夹，然
后通过测试夹内的金属钩连接被测信号节点，如图 2所示。

3．设置探头：按示波器前面板上的 LA 按键进入探头设置菜单，用户可在
该菜单下查看和设置如下参数：阈值电平(D0-D7 与D8-D15 分组阈值
电平独立调节)、波形大小(应用于所有通道，其中 L选项只在屏幕活动
通道数不多于 8时可用)、通道标签和探头校准等。
注意：若探头第一次连接到该示波器或者环境温度变化 5℃以上，建议
利用 LA 菜单下自校准功能进行零点自校准，校准时保持 RPL1116 输入
端不接信号。
4．功能检查：完成上述操作后，被测信号将显示在示波器屏幕上相应的数
字通道上。如果看不到信号，请调节示波器选择合适的触发方式和时基
等常规设置。如果仍然看不到信号，请再次检查电气连接和参数设置，
或者尝试使用其他探头(如模拟探头)来验证测试点的信号状态。

Product Overview
As 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. 20 input signal
leads and 20 grabbers are provided as standard configurations for
RPL1116 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.

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

- 4 -
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 requirements. 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 1: 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: The crosstalk or ground bounce during use may be
caused by the fact that the channels share a single ground lead.
Therefore, you are recommended to add one ground wire to the
signal lines of each channel and twist them.
Method 2: on the basis of Method 1, you can connect a grabber
to each lead and connect it to the device under test as shown in

3．Set the probe: press LA on 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, 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. Please disconnect all the signals from the
RPL1116 input terminal during the calibration.
4．Function Inspection: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 the problem still persists, please
check the electric connection and parameter settings again or please
try to use other probes (such as analog probe) to check the signal
state of the test point.
