Application Notes
Model 370 Curve Tracer Procedure Notes
Because the curve tracer procedures in this application note are
written for the Tektronix model 576 curve tracer, certain settings
must be adjusted when using model 370. Variable Collector Sup-
ply Voltage Range and Power Dissipation controls have different
scales than model 576. The following table shows the guidelines
for setting Power Dissipation when using model 370.
(Figure AN1006.27)
Model 576
If power dissipation is 0.1 W,
If power dissipation is 0.5 W,
If power dissipation is 2.2 W,
If power dissipation is 10 W,
If power dissipation is 50 W,
If power dissipation is 220 W,
Model 370
set at 0.08 W.
set at 0.4 W.
set at 2 W.
set at 10 W.
set at 50 W.
set at 220 W.
Although the maximum power setting on the model 370 curve
tracer is 200 W, the maximum collector voltage available is only
400 V at 220 W. The following table shows the guidelines for
adapting Collector Supply Voltage Range settings for model 370
curve tracer procedures:
Model 576
If voltage range is 15 V,
If voltage range is 75 V,
If voltage range is 350 V,
If voltage range is 1500 V,
Model 370
set at 16 V.
set at 80 V.
set at 400 V.
set at 2000 V.
The following table shows the guidelines for adapting terminal
selector knob settings for model 370 curve tracer procedures:
Model 576
If Step generator (base) is emitter grounded,
If Emitter grounded is open base,
Model 370
then Base Step generator is
emitter common.
then Base open is emitter
common.
