The RIGOL PLA2216 is a 16-channel active logic probe designed to connect digital signals from a device under test to compatible RIGOL mixed-signal oscilloscopes. It enables simultaneous observation and analysis of multiple digital lines alongside analog oscilloscope channels, making it suitable for embedded-system development, digital circuit troubleshooting and hardware verification.
The probe provides 16 digital inputs labeled D0–D15. These channels are organized into two groups, D0–D7 and D8–D15, allowing the threshold level of each eight-channel group to be adjusted independently through the oscilloscope’s logic-analyzer menu.
16-Channel Digital Signal Acquisition
Users can connect any number of signals up to the full 16-channel capacity. This makes the PLA2216 suitable for monitoring address lines, data buses, control signals and other related digital events within complex electronic systems.
Channel labels on the probe and input leads make individual signals easier to identify during multi-channel measurements.
Mixed-Signal Circuit Analysis
When connected to a compatible RIGOL oscilloscope, the PLA2216 enables digital waveforms to be viewed together with analog signals. This mixed-signal capability helps engineers examine timing relationships between digital control activity and analog circuit behavior on the same test platform.
Flexible Signal Connections
The probe supports direct lead connections or connection through the supplied grabber clips. Twenty signal leads and twenty grabbers are provided, offering flexible access to signal points and reference grounds on development boards, prototypes and assembled circuits.

Oscilloscope Compatibility
The PLA2216 is officially specified for the following RIGOL oscilloscope families:
- RIGOL DHO900 Series
- RIGOL DHO900S Series
- RIGOL MSO5000 Series
Before ordering, confirm that the exact oscilloscope model has the required front-panel digital input and supports the logic-analyzer function. The PLA2216 is a specialized active probe and should not be treated as a universal logic probe for unrelated oscilloscope series.

Why Choose the RIGOL PLA2216?
The PLA2216 is the appropriate logic probe for users who need to add up to 16 digital measurement channels to a compatible RIGOL DHO900/S or MSO5000 oscilloscope. Its two independently configurable threshold groups, flexible connection accessories and mixed-signal workflow make it especially useful for diagnosing timing and logic relationships that cannot be evaluated with analog channels alone.
