Connecting Introspect’s RSH2 Remote Sampling Head to Any Oscilloscope

Why This Matters for Lab Teams

Introspect Technology recently revisited one of the most common questions their applications engineers receive: “Can the RSH2 Remote Sampling Head plug into any oscilloscope?” Their answer is an enthusiastic yes—the RSH2 mates with any 50 Ω instrument—making it a clever way to extend the reach of your existing scopes without adding boutique probe heads for every vendor.

For Primeasure customers running Teledyne LeCroy, Keysight, Rohde & Schwarz, or Tektronix platforms side by side, this compatibility story is powerful. A single remote head can live near the device under test while long, lossy probe leads disappear. Introspect’s write-up inspired us to capture the key takeaways along with a few extra notes from the field.

What Makes the RSH2 Different

• Twelve active probes in one chassis: The RSH2 brings enough channels to fan across parallel buses such as MIPI CSI-2 or D-PHY while keeping the bench uncluttered.
• Minimal loading on the DUT: Each probe is buffered, so sensitive, low-voltage lanes are preserved even when the scope input is a 50 Ω termination.
• Universal 50 Ω output: A standard coax or SMPM cable does the final hop into whatever oscilloscope is free—no adapter forests or vendor lock-in.
• Compact remote head: Sitting the head on the DUT keeps high-speed runs short and controlled, while the heavier oscilloscope remains on the cart.

Recreating Introspect’s Smartphone Camera Demo

Introspect demonstrated the RSH2 by probing a live smartphone camera link. Probe tips were soldered directly onto the application processor and camera interface, then routed through an SMPM adapter into the remote head. From there, a 50 Ω cable carried each lane to the oscilloscope.

The screenshots they shared highlight:

• Figure 1: A tidy bench setup with the handset on a fixture, the RSH2 close to the target, and only coax cables looping back to the oscilloscope.
• Figure 2: A clean D-PHY eye diagram captured in real time, demonstrating that the active probes preserve rise-time fidelity.
• Figure 3: An oscilloscope overlay of the data lanes showing minimal crosstalk even with two channels instrumented simultaneously.

While we can’t redistribute their imagery here, the original article is worth a read for visuals and additional commentary. The workflow echoes what our automotive and handset customers are doing day to day.

Checklist for Your Own Lab

1. Plan probe points early: Layout pads or flying leads that will accept the RSH2’s solder-in tips without crowding adjacent components.
2. Use quality coax: Keep the run between the RSH2 and the oscilloscope short and rated to the bandwidth you expect to measure.
3. Terminate correctly: Leave the scope in 50 Ω mode to maintain signal integrity; the RSH2 is already conditioned for that impedance.
4. Correlate with protocol tools: Pair the scope view with protocol decodes or traffic captures so you can tie waveform shape to packet context.
5. Document fixture settings: Capture probe placement, cable lengths, and any deskew operations so the setup is repeatable across shifts.
