Packed Mode (Remote Command Only)
Selects the packed mode for Demod bits in SCPI result (of READ:CDP12).
•
OFF: Demod Bits are not packed. (1.0:“1”, 0.0:“0”, –1.0:“X”)
•
PKM1: Demod Bits per symbol is packed into 1 float value in bit-slice manner as follows:
64QAM(No DTX)
Float value 0……X5X4X3X2X1X0 (X5:I1, X4:Q1, X3:I2, X2:Q2, X1:I3, X0:Q3)
16QAM(No DTX)
Float value 0……0X3X2X1X0 (X3:I1, X2:Q1, X1:I2, X0:Q2)
QPSK(With DTX)
Float value 0……0M1M0B1B01
4PAM (No DTX)
Float value 0……0 I1 I2 Q1 Q2
4PAM on I branch
and BPSK on Q
branch (No DTX)
Float value 0……0 I1 I2 0 Q
BPSK on I branch
and 4PAM on Q
branch (No DTX)
Float value 0……0 0 I Q1 Q2
Table Note 1: The meaning of each bit is
•
M1:Mask for B1 (1:DTX, 0:Normal)
•
M0:Mask for B0, and B1:I, B0:Q)
Packed Mode is only available via the SCPI command, and changing Packed Mode does not bring any
change on the results of Front panel display. It only controls the result format of READ
(MEAS/FETCH/CONF):CDP12.
