Multichannel cdma2000
personality
(Option 101, ESG-DP and ESG-D series only)
This personality conforms to cdma2000 specification
revision 8. Provides partially coded data for component test appli-
cations.

IS-95 filter selection
All are IS-95 compliant. “Modified” filters reduce spurious
emissions for adjacent channel power measurements.
