Introduction

A direct MMCX connection for the PCBite SQG15 and SQG30. The shortest possible ground path for clean measurements on power supplies, analog circuits and other sensitive signals.

The MMCX adapter fits the 3.5 mm (0.14 in) probe head of the PCBite SQG15 and SQG30 and connects the probe signal and ground directly to an MMCX connector on the PCB. The ground path becomes as short as possible, which keeps noise pickup to a minimum.

This matters most on sensitive circuits such as power supply designs and analog stages. With almost no noise picked up through the ground path, ripple on supply rails can be measured accurately instead of disappearing in probe noise.

With the MMCX adapter, the SQG15-AC and SQG15-DC keep their full 1.5 GHz bandwidth. On the SQG30-AC and SQG30-DC the adapter adds length to the signal path, which places the −3 dB bandwidth at about 2.6 GHz. Above that the probe continues to measure, with a gradually lower signal.

MULTIPLE POINTS

Many test points. One probe.

Place MMCX connectors at several points on the board and move the probe from one to the next in seconds. With connectors at the input and output of a power supply, you can see whether noise enters or leaves through it. One probe is enough to scan many points quickly.

SOLDER ON

Add a shielded test point.

No MMCX footprint is required in the PCB layout. Expose a small area of copper at the signal and a nearby ground, then solder an MMCX connector directly to the board. This creates a short coaxial connection for measurements at points such as a regulator output or ADC input, while minimizing noise pickup.

REPEATABLE

Same point. Comparable results.

The snap-on connection meets the board at the same point every time. Measure before and after a design change, or compare several boards, without differences in probe placement affecting the result.
