Technical data

<PACKed>: permits the packing of bits within a byte to be set.
<NR1>: Can be 1, 4, or 8.
1 | 4 | 8
The command controls the format of data transfer for
the :PATTern:UPATtern<n>:DATA, :PATTern:UPATtern<n>:IDATa, :PATTern:UFIL
e:DATA and :PATTern:UFILe:IDATa commands. The following values are possible:
• 1
The data is sent as a string of 1s and 0s.
• 4
The data is sent as a string of hex characters.
• 8
The data is sent as a string of full 8-bit ASCII characters.
The query returns the current value of the data pack.
See “Working with User Patterns in SCPI” on page 63 for descriptions on how to
use the data packing.

[SOURce[1]]:PATTern:MDENsity[:DENSity]?
<NR2>: 0.125, 0.25, 0.5, 0.75, 0.875
The command sets the ratio of high bits to the total number of bits in the pattern.
The ratio may be varied in eighths, from one to seven (eighths), but excluding three
and five.
The query returns the mark density in eighths.
