产品简介
RPL2316 是一款高性能逻辑探头，可将待
测系统上的数字总线及信号连接至
RIGOL MSO4000 系列数字示波器。
RPL2316 的16 个数字通道分为两个支线
端，称为通道组。每个通道组包含 8个信
号通道(D0-D7 和D8-D15)和12 个接地通
道。在探头适配器的标签上所有通道都用
不同的颜色和数字（或字母）清晰标示，便于区分不同的通道。RPL2316 为
每个通道组标配 8根前端信号引线和 2根接地引线，可用于灵活的连接被测
信号和参考地，并提供更好的信号完整性。注意：在任何情况下都必须确保
探头适配器与通道组的可靠连接。

逻辑探头的使用方法
1．连接 RPL2316 至示波器：上下按压逻辑探头单线端两侧的按钮，按照
下图箭头所指方向垂直连接至 MSO4000 系列数字示波器前面板的
[LOGIC D0-D15]接口。注 意 ：“ RIGOL”字样朝上，标签朝下。
2．连接被测信号至 RPL2316：用户可以根据测试需要将任意数量（≤16）
的被测信号连接至 RPL2316，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。为适应不同的应用场合，RPL2316 提供了

三种与被测信号的连接方法。
方法一：用户可将 RPL2316 与预留在待测设备上的双排金针直接
连接，此时，RPL2316 必须保留适配器的连接。如图 1所示。
方法二：用户可通过前端引线单独连接各个被测信号，此时
RPL2316 必须保留适配器的连接。通过前端引线上的色环以及适
配器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 2
所示。

图2
方法三：在方法二的基础上，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 3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)、通道标签和数字总线(提供 2条独立的专用
数字总线，可分别设置时钟、位宽、显示格式及噪声抑制等，如需更多
灵活功能请参考并选用通用总线)。
4．功能检查：完成上述操作后，被测信号将显示在与连接相对应的通道上。
如果看不到活动信号，请调节示波器选择合适的触发方式和时基等常规
设置。如果仍然看不到活动信号，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
Being a high performance logic probe,
RPL2316 connects the digital buses
and signals under test to the
MSO4000 series digital oscilloscope.
RPL2316 separates 16 digital
channels into two branch headers,
called channel group. Each header
includes 8 signal channels (D0-D7 and D8-D15) plus 12 ground channels. All
the channels are marked with different colors and numbers (or letters) on
the probe adaptor label to identify different channels. RPL2316 provides 8
signal leads and 12 ground leads for each header to realize flexible
connection of signals and reference ground and provide better signal
integrity. Note: in any case, make sure that the connection between probe
adapter and the channel group is reliable.

The Using Method of the Logic Probe
1．Connect RPL2316 to the oscilloscope: push the buttons on both
sides of the logic probe single head and connect it (with “RIGOL”
facing upward and the label facing downward) to the digital channel
input terminal [LOGIC D0-D15] at the front panel of the MSO4000
series digital oscilloscope in the arrow direction as shown in the figure
below.

2．Connect the signals under test to RPL2316: users can connect
any number (≤16) of the signals under test to RPL2316 in according to
the test need. Make sure that the amplitude of the input signal should
not exceed the maximum working voltage range while connecting.
RPL2316 provides three connection methods with the signals under
test for different applications.
Method one: you can connect RPL2316 to the two rows of pins
on the device under test directly. At this point, the probe adaptor
must be connected as shown in figure 1.
Method two: you can connect the signals under test through
leads separately. At this point, the probe adaptor must be
connected as shown in figure 2. You can easily identify the
corresponding channel of each signal by the color rings on the
leads and the color information on the adaptor.

Figure 2
Method three: on the basis of method two, you can connect a
grabber to each lead and connect it to the device under test as
shown in figure 3.

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 and
digital bus (provide 2 independent digital buses to set various
parameters respectively, such as the clock, bit width, display format
and noise rejection; for more flexible functions, use common bus).
4．Function Check: after finishing the above operations, the signal
under test will be displayed on the corresponding channel. If no active
signal is displayed, please adjust the oscilloscope to select proper
general settings (such as the trigger mode and timebase). If active
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.
