Some of the probing solutions I have developed for use in my own lab:
Disposable Near Field Probe
Low cost partially shielded 5.0 mm x 7.0 mm NF probe with 3 mm sensing trace.
The probe can be mounted on your PCB or ICs with double sided tape for EMC/ESD troubleshooting or IC signature measurement.
The probe kit contains 8 disposable NF probes. Two short 100 mm cables with SMA female connectors are included in the kit.
Please contact us for details.

Disposable X-Y Near Field Probe
Low cost 2 channel (X-Y) partially shielded 15.0 mm x 15.0 mm NF probe with 13.2 mm sensing traces.
The probe can be mounted on your PCB or on ICs with double sided tape for EMC/ESD troubleshooting or IC signature measurement.
The probe kit contains two X-Y NF probes. Four short 100 mm cables with SMA female connectors are included in the kit.
Please contact me for details.

Disposable 1.5 GHz Passive 500 ohm Probe
Low cost 6.5 mm x 14.0 mm passive probe for oscilloscopes with 50 ohm inputs.
The probe can be mounted on your PCB with double sided tape.
Maximum probe voltage rating: 5V RMS, 15V Peak.
The probe kit contains 4 probes. Two short 100 mm cables with SMA female connectors are included in the kit.
Please contact me for details.

Amplitude frequency response (typical) for the 1.5GHz passive 500 ohm probe.
The attenuation is a little more than the 20:1 probe attenuation because the 25 ohm source is loaded with the 500ohm probe.
Example: Probing a 1.0 Vpp 500MHz clock signal (CG635) with the 1.5GHz 20:1 probe and a 4 GHz RTO1044 oscilloscope. The white trace is the signal from the CG635 and the yellow trace is the signal from the probe. Mini circuits hand-flex cables are used in both cases.
Disposable 4 Channel 1.5 GHz Passive 1k ohm Probe
Low cost 21.74 mm x 14.0 mm quad channel passive probe for oscilloscopes with 50 ohm inputs.
The probe can be mounted on your PCB with double sided tape.
Maximum probe voltage rating: 5V RMS, 15V Peak.
The probe kit contains 1 four channel probe. Four short 100 mm cables with SMA female connectors are included in the kit.

Amplitude frequency response (typical) for the quad 1.5GHz passive 1000 ohm probe.
Example: Probing a 1.0 Vpp 500MHz clock signal (CG635) with the quad 1.5GHz 40:1 probe and a 4 GHz RTO1044 oscilloscope. The white trace is the signal from the CG635 and the yellow trace is the signal from the probe. Mini circuits hand flex cables are used in both cases.
