[time-nuts] Tektronix AM503X current probes

[Henk ten Pierick]

Hi,

Tektronix made two types of current probes, AC probes and Dc probes.  
The AC probes go from some Hz or kHz upto Mhz or GHz. They are robust  
and not so expensive. The DC probes  are ac probes with an additional  
hall sensor in it. The go from DC to say 100MHz. The DC probes are  
expensive and the hall sensor is easily damaged by a drop on the  
floor. At least, that is my experience. If you want to by a current  
probe and need a DC  probe, take care that the hall sensor is not  
damaged.

regards,

Henk
