4-16 Fully Coded 3GPP W-CDMA Personality User’s and Programming Guide
Operation ESG Family Signal Generators
Understanding W-CDMA Data Generation Option 200
DPDCH
General restriction: In order for the ESG to precompute data for baseband generation, you
must press the
Apply Channel Setup after any one of following actions:
• Changing any DPDCH parameter value (except for power)
• Changing from any other channel type to DPDCH
• Changing from DPDCH to any other channel type
Transport Channel Layer
General restriction: In order for the ESG to precompute data for baseband generation, you
must press the
Apply Channel Setup after changing any parameter value.
• DCHs must be turned on sequentially (DCH 1 and 2 must be ON before DCH 3 is
activated).

Parameter Restrictions Notes
Blk Size Max user file size =
4096 bytes
Coupled to Bits Rate, Bits/Frame, and other values.
“information bits”/TTI = “block size” * “num of blocks”
Num of Blks Max 4095 blocks
Coding None Coupled to Bits Rate, Bits/Frame, and other values.
TTI None Coupled to Bits Rate, Bits Rate, and other values.
Data Max user file size =
1024 bits
Transmission of user files larger than 1024 bits will be
truncated to a multiple of the block size.
Rate Match
Attr
None Coupled to Bits Rate, Bits/Frame, and other values.
CRC Size None
Bits/Frame Not user selectable. Data field for value display only, to provide total information
data bits-per-radio frame. Value based on Blk Size, TTI, Coding
and Rate Match Attr values.
