blocks.

Possible values:
for S4539: 1 to 7
By means of this function the operator can
change the number of modem Tx level control
blocks used at the beginning of a transmis-
sion. Those additional data probes in front of a
transmission enable the radio TLC (transmitter
level control) as well as the radio and modem
AGC (automatic gain control) to settle the sig-
nal level without disturbing payload data.
This parameter should be increased if the
used gain control attack time (e.g. from a third
party radio or modem supplier) is long. The
STANAG 4539 implementation in the Rohde
& Schwarz radio has been optimized, thus for
homogenous Rohde & Schwarz equipment a
value of 1 is recommended.
This parameter is adjustable for HF Modem
type STANAG 4539 only.
