Description
Tells cmd5318 to generate a configuration output file for general use.
Tells cmd5318 to generate a configuration output file for GC101 use.
Tells cmd5318 to generate a analysis output file
Tells cmd5318 to generate a table output file
Tells cmd5318 to generate an approximate power consumption output
file.
Used to calculate transmit tuning frequencies
All controls after this keyword apply to this DUC channel
Copy the DUC channel commands from the specified channel to the
current channel
Sets the NCO tuning frequency for the UMTS channel or for the a-path
in the current channel if in CDMA mode.
Sets the NCO tuning frequency for the b-path in the current channel if in
CDMA mode.
Specifies the filename containing the pfir taps
Specifies the filename containing the cfir taps
Optional—Specifies the overall gain for the UMTS channel or the a-path
in the current channel if in CDMA mode.
Optional—Specifies the overall gain for the b-path in the current channel
if in CDMA mode.

Description
EVM signal select control must be set to 0.
EVM signal select control-txin_[0:5]_[a:b] ports.
EVM signal select control-txin_[6:11]_[a:b] ports.
00 = txout_a enabled, 01 – txout_c enabled, 10—not used, 11—not used.
00 = txout_b enabled, 01 – txout_d enabled, 10—not used, 11—not used.
When asserted, the 2 LSBs each of active txout are output to GC101, else
the various strobes/syncouts are output.
(if txout_lsb = 0) selects which signals are output. 00-tx_sync_out +
tx_i_flag, 01–sync_tst + aflag_tst, 10-tx_sync_out0 + interrupt.
(if txout_lsb = 0) when 00, test 9 + test11 is output , test7 + test8 data is
output.
Selects the output clock source. 00 – txclk_out, 01-clk_tst, 10-clkout+.
Not used.
