FreeLists / si-list / [SI-LIST] Low Load Probe Suggestions

["Mark Randol" <Mark.Randol@xxxxxxxxxx>]

I realize this is like asking gear heads what motor oil they prefer, but
for low loading what probes do you prefer?  I know what I've used, but
just wondering what else might be available.

I'd prefer <1pF capacitance and at least 100kohm resistance.  Bandwidth
up to at least 500MHz, preferably into GHz.  Low frequency should push
towards 10kHz.  Tip voltages typically <5V, almost always <15V.  Some
wiggle room is allowed in the 'specs'.

Regards,
