4.2.3 Operations in Sweep Source Mode
4-15
1. Setting the sweep type
• Select DC Sweep or Pulse Sweep by using the soft key MODE.
• Select Linear, MLinear, Log, Random or Fixed by using the soft key SWPType.
Pulse
sweep
PLSSWP
Linear sweep
Linear
Generates staircase pulse waveforms of the step value
between the start value and the stop value.
Kth output value = Start value +
(K - 1)
× (Step value)
Number of steps = (|Stop value – Start value|) /
(Step value) +1
Multi-Slope Linear
Sweep
MLinear
Generates staircase pulse waveforms of different slopes
by specifying the number of slopes between 2 and 4.
1st slope:
Kth output value = First value +
(K - 1)
× (1st step value)
Number of steps = (|Second value - First value|) /
(1st step value) +1
2nd slope:
Kth output value = Second value +
(K - 1)
× (2st step value)
Number of steps = (|Last value - Second value|) /
(2nd step value) +1
Log sweep
Log
Generates staircase pulse waveforms logarithmically
divided by the number of steps by decade.
Kth output value = Start value
× S
S = 10
(K - 1) / n
n: Number of partitions by decade
(1, 2, 5, 10, 25, 50)
• Start value, Stop value 0
• |Start value| | Stop value|
• Start value polarity = Stop value polarity
Random sweep
Random
Generates pulse waveforms of the source values stored
in the memory from the start address to the stop
address.
Fixed level sweep
Fixed
Generates pulse waveforms of the specified level by the
specified sampling count.
