Technical data

• AuxInHi | AuxInLo: Sequence starts when Auxiliary Input is high or low.

• AuxInRising | AuxInFalling: Sequence starts with a rising or falling edge at the

Auxiliary Input.

• Manual: Sequence starts when the [SOURce[1]]:PATTern:SEQ:EVENt ONCE

command is received.

Example:

Start= AuxInRising

Defines the contents of a block and the On/Off of the associated sequence trigger.

Syntax:

Block #= <PatternType1.0> [, TrigOn |, TrigOff]

Block #= <PatternType1.1> [, TrigOn |, TrigOff]

The range of "#" is 1 to 120.

N O T E

A sequence consists of up to 120 blocks that can be looped. The sum of blocks and

counted loops must not exceed 120.

Input parameters:

• For version 1.0, the PatternType is one of the following:

[<Length>] | CL/#[, <Length>]

For version 1.1, the PatternType is one of the following:

None,X| PRBS#,Y,[, <Length>] | <UserFilename>[,A|,B],Y, [, <Length>] |

P0,Y[, <Length>]| P1, Y[, <Length>] | CL/#,Y[, <Length>]

Where:

X = None

Y = PRBS#| <UserFilename>[,A|,B] | P0| P1,| CL/#

N O T E

Length is related to master channel (Data Out) while the other channel (Aux Data)

will always follow this length.

N O T E

'None' is only possible for both channel synchronically.

Example: Block 1= None, None, 311040, TrigOn is possible

Example: Block 1=None, P1, 311040, TrigOn is not possible

The default length of a block is 512 bits. Therefore, this parameter can be

omitted.
