7CT1N
The 7CT1N is a curve tracer plug-in for 7000-series scopes.
Common Problems
C30 and C32 (100 uF, 25V)have a tendency to leak or short, causing associated resistors R30 and R32 (240, .25W, 5%) to overheat and fail. A good preventative maintenance procedure would be to replace these two capacitors with modern equivalents. Three 7CT1N units purchased online had this fault, and replacement of the capacitors and resistors restored proper operation.
