Procedure 3: (-) V
DRM
and (-) I
DRM
To measure the (-)V
DRM
and (-)I
DRM
parameter:
1. Set
Polarity
to (–).
2. Repeat Procedures 1 and 2. (Read measurements from
upper right corner of the screen).
Procedure 4: V
BO
and I
BO
To measure the V
BO
and I
BO
parameter:
1. Set
Variable Collector Supply Voltage Range
to
1500 Max
Peak Volts.
(
2000 V
on 370)
2. Set
Horizontal
knob to a sufficient scale to allow viewing of
trace at the required voltage level (
50 V/DIV
for 95 V to
215 V V
BO
range devices and
100 V/DIV
for devices having
V
BO
≥
15 V).
3. Set
Vertical
knob to
50 μA/DIV.
4. Set
Polarity
to
AC.
5. Set
Mode
to
Norm
.
6. Set
Power Dissipation
to
10 W
.
7. Set
Terminal Selector
to
Emitter Grounded-Open Base
.
8. Set
Left-Right Terminal Jack Selector
to correspond with
location of test fixture.
Procedure 5: V
BO
To measure the V
BO
parameter, increase
Variable Collector
Supply Voltage
until breakover occurs. (Figure AN1006.23) The
voltage at which current begins to flow and voltage on CRT does
not increase is the V
BO
value.
Figure AN1006.23 (+)V
BO
= 100 V; (-)V
BO
= 100 V; (±)I
BO
< 10 μA
Procedure 6: I
BO
To measure the I
parameter, at the V
point, measure the
amount of device current just before the device reaches the
breakover mode. The measured current at this point is the I
BO
value.
Note: If I
BO
is less than 10 μA, the current cannot readily be seen
on the curve tracer.
Procedure 7: I
H(Forward and Reverse)
To measure the I
H (Forward and Reverse)
parameter:
1. Set
Variable Collector Supply Voltage Range
to
1500 Max
Peak Volts
(
400 V
on 577;
2000 V
on 370).
2. Set
Horizontal
knob to a sufficient scale to allow viewing of
trace at the required voltage level (
50 V/DIV
for devices with
V
BO
range from 95 V to 215 V and
100 V/DIV
for devices
having V
BO
≥
215 V).
3. Set
Vertical
knob to 20% of maximum holding current speci-
fied.
4. Set
Polarity
to
AC.
5. Set
Mode
to
Norm.
6. Set
Power Dissipation
to
220 W
(
100 W
on 577).
7. Set
Terminal Selector
to
Emitter Grounded-Open Base.
8. Set
Left-Right Terminal Jack Selector
to correspond with
the location of the test fixture.
WARNING: Limit test time to 15 seconds maximum.
9. Increase
Variable Collector Supply Voltage
until device
breaks over and turns on. (Figure AN1006.24)
Figure AN1006.24 I
H
= 48 mA in both forward and reverse
directions
I
is the vertical distance between the center horizontal axis and
the beginning of the line located on center vertical axis.
Procedure 8: V
TM(Forward and Reverse)
To measure the V
TM (Forward and Reverse)
parameter:
1. Set
Variable Collector Supply Voltage Range
to
350 Max
Peak Volts.
(
400 V
on 370)
2. Set
Horizontal
knob to
0.5 V/DIV.
3. Set
Vertical
knob to
0.5 A/DIV.
4. Set
Polarity
to (+).
5. Set
Mode
to
Norm.
6. Set
Power Dissipation
to
220 W
(
100 W
on 577).
7. Set
Terminal Selector
to
Emitter Grounded-Open Base.
Before continuing with testing, note the following:
A Kelvin test fixture is required for this test. If a Kelvin fixture is
not used, an error in measurement of V
TM
will result due to volt-
age drop in fixture. If a Kelvin fixture is not available,
Figure AN1006.3 shows necessary information to wire a test
fixture with Kelvin Connections.
