2 P5150 probes are intended for use with oscilloscopes that have isolated ( fl oating) inputs. The Tektronix TPS2024B and THS3024 oscilloscopes
are the highest bandwidth fl oating-input oscilloscopes currently available. If you do not have access to one of these oscilloscopes, use the
recommended ground-referenced model.
Access the Adjustments
To gain access to the adjustments, you must slide the cover off of the probe body. Insert a thin fl at-blade screwdriver into the
slot on the top of the compensation box and slide back the cover. (See Figure 13.)
