[:SOURce]:FUNCtion[:SHAPe]
Syntax [:SOUR]:FUNC[:SHAP][?]
Form Set & Query
Description Defines the main mode of the signal to be generated
(pulse/pattern, burst, or repetitive burst mode).
Parameter PATTern|BURSt, <numeric>|RBURSt, <numeric>, <numeric>
•PATTern
In this mode, each channel can be set independently to generate:
– Square waves of fixed width
– Pulses with selectable width or duty cycle
– Data in either RZ, R1 or NRZ format
– Pseudo random bit stream (PRBS) polynomials
To generate these signals, use “[:SOURce]:FUNCtion:MODe[1|2]”
on page 51.
• BURSt, <number of repeated data>
This mode enables you to generate a burst consisting of data
repeated n times followed by continuous zero data.
*RST value: 1
• RBURSt, <number of repeated data>, <p>
This mode enables you to generate a repeated burst consisting of
data repeated n times. A pause of zeros is inserted between two
successive bursts. The pause of zeros is calculated by:
Length of the pause = Burst Length × p
*RST values: 4, 4
*RST value PATT
Example Generate a burst of data repeated 5 times:
