The 7CT1N is a [[curve tracer]] plug-in for [[7000-series scopes]]. | The 7CT1N is a [[curve tracer]] plug-in for [[7000-series scopes]]. | ||
It can be installed in either a vertical or a horizontal compartment, a front-panel switch must be set accordingly. | |||
A pull-out cable with a plastic BNC plug connects to the input of a module installed in the corresponding | |||
plugin for the other axis, with a fixed 100 mV/Div scaling compatible with time base X inputs. | |||
Internally, a variable-amplitude 55 Hz triangle-wave source supplies a transformer to step up the drive voltage and | |||
decouple it from ground (Emitter terminal). A step source supplies base current or gate voltage to the DUT. | |||
The amplifier for the current axis can be switched into a x1000 mode | |||
to detect leakage currents (of typical 1970s semiconductors, anyway). | |||
