Due to the isolated inputs, the probe ground must be connected even when | |||
compensating the probes with the "PROBE COMP" output. It can be used with | |||
any BNC probe but the scale factor pin found on many Tektronix probes is | |||
not used. The vertical menu has a scale factor entry (1X, 10X, 100X, 1000X) | |||
which can also be used for direct BNC inputs. | |||
Recommended probes are the [[P5102]] and the [[P6113B]], both are 10X probes | |||
with protected grounds for isolated measurements. | |||
