Adjustment by Switch
2-2
2.1 Adjustment by Switch
-
S1 toggles between high (direction labelling) or low transient generator
frequency.
-
S2 switches the transient generator on (direction labelling) and off.
-
S3 toggles between slower (direction labelling) and faster transients.
-
S4 directs transients either to DUT1 (direction labelling) or DUT2.
2.2 Adjustment by Jumper
Table 2–1 lists adjustments that can be made by jumpers.
Table 2–1. Jumper Functions
Function/Device DUT1 DUT2
Bypasses input resistor JP1 JP10
Enables DUT JP2 JP7
Bypasses ESR emulation JP3 JP8
Set minimum load JP4 JP9
Set maximum load JP5 JP11
Toggles between input voltage (direction trimmer) and load
transient JP6 JP12
2.3 Adjustment by Trimmer
Table 2–2 lists the adjustments that can be made by trimmer.
Table 2–2. Trimmer Adjustments
Function/Device DUT1 DUT2
Risetime of transient R15 R32
Input voltage spike transient impact R12 R28
2.4 Adjustment by Programming Header
The programming header can be used to program the frequency and the duty
cycle of the transient generator. Table 2–3 lists the timing equations.
