ITEM
NAME
FUNCTION
11
400 ohm OUTPUT
jack
The impulse waveform appears on the
OUTPUT
jack, referenced to the
RETURN
jack.
When the
POLARITY
switch is in the Normal position (
NOR
indicator is lit) the output will be a positive pulse.
When the
POLARITY
switch is in the Reverse position (
REV
indicator is lit) the output will be a negative pulse.
12
AUX
OUTPUT
jack
The
AUX OUTPUT
is connected at the grounded side of the 100ohm resistor, but this output is only used when it is required to
float the 100ohm resistor.
13
MEAS. POINT
jack
Used to perform the Pass/Fail reference test.
14
Y1 – Y2
outputs
These differential outputs are to be connected to two different channels of an oscilloscope. The outputs are then subtracted and
the resulting waveform is used to judge acceptability of the EUT.
15
ENERGY MEAS.
switch
By pressing this switch, the front display will blink showing for a few seconds the energy measurement from the last pulse.
Note: This function only works when the MegaPulse unit is not charging or triggering.
16
PASS FAIL REF.
switch
The D5-PF Includes the Pass-Fail reference circuit built in, to use properly refer to the directions on front panel.
17
PASS FAIL REF.
indicator
This Green indicator is lit to show that the pass/fail reference is connected (AUX OUTPUT must be grounded).
18
AUX OUTPUT
switch
It is used to control the AUX output position (Floated or Grounded).
19
AUX OUTPUT
indicator
This Green indicator is lit to show that
AUX OUPUT
switch is set on the
FLOAT
position.
20
S3
switch
Used for common mode testing of figure 201.103, S3 switch should be closed only when auxiliary output is floated from ground.
21
S3
indicator
This Green indicator is lit to show that
S3
switch is set on the
SHORT
position.
22
INDUCTOR
left switch
This switch allows the user to select the inductance value between 500uH and 25mH.
23
INDUCTOR
right switch
This switch allows the user to select the inductance resistance value between 10 ohm and 11ohm when INDUCTOR left switch is
on 25mH.
24
S2
left
switch
This switch is provided to protect the Signal Generator from the output pulse of the D5-PF when OFF, and to allow the required
20V p-p signal to be injected when SINE WAVE is selected.
25
S2
right
switch
This switch is enable only when S2 left switch is on SINE WAVE position and allows selecting between 390K or 470K ohm.
26
BNC INPUT 10Hz, 22Vp-p
BNC Input provided on front panel is for connecting the output signal generator. See Figure 12 Part 9A.
Note:
If the unit includes the Sine Wave Generation option, the item 26 will be a BNC OUTPUT 10Hz, for monitoring the Sine
Wave with an oscilloscope.
27
COARSE
adjustment (optional)
It is used to adjust the amplitude of the sine waveform. Only for models with Sine Wave Generation option.
28
FINE
adjustment (optional)
It is used to fine adjust the amplitude of the sine waveform. Only for models with Sine Wave Generation option.
