Command Syntax:
{:ATC |:ATC5000NG}{:DO260}{:TYPE}{:OVERLAPPINGPULSE |:OVERLAP}{:PULSE} {:WIDTH
|:WID}SP<numeric>CR
Description:
This command sets the overlapping pulse width.
Numeric:
0 to 130000 ns (decimal ASCII)
Example:
:ATC:DO260:TYPE:OVERLAP:PULSE:WIDTH 4500\r
Default:
0 ns
Query:
:ATC:DO260:TYPE:OVERLAP:PULSE:WIDTH?\r
Return:
4500
Command Syntax:
{:ATC |:ATC5000NG}{:DO260}{:TYPE}{:PREAMBLEVAL |:PREA }
{:CHIPS}{:DAMP}SP<numeric>CR
Description:
This command sets the delta amplitude in dB for energy bits of the pulse.
Numeric:
-10 to 10 dB (decimal ASCII).
Example:
:ATC:DO260:TYPE:PREA:CHIPS:DAMP -6\r
Default:
0 dB
Query:
:ATC:DO260:TYPE:PREA:CHIPS:DAMP?\r
Return:
-6
Command Syntax:
{:ATC |:ATC5000NG}{:DO260}{:TYPE}{:PREAMBLEVAL |:PREA }
{:CHIPS}{:EFIRST}SP<numeric>CR
Description:
This command sets the first energy bit of the message with amplitude.
Numeric:
0 for no bad chip (decimal ASCII)
1 to 112 if the reference is a long Mode S (decimal ASCII)
1 to 56 if the reference is a short Mode S (decimal ASCII)
Example:
:ATC:DO260:TYPE:PREA:CHIPS:EFIRST 1\r
Default:
0
Query:
:ATC:DO260:TYPE:PREA:CHIPS:EFIRST?\r
Return:
1
Command Syntax:
{:ATC |:ATC5000NG}{:DO260}{:TYPE}{:PREAMBLEVAL |:PREA }
{:CHIPS}{:NFIRST}SP<numeric>CR
Description:
This command sets the first no energy bit of the message.
Numeric:
0 for no bad chip (decimal ASCII)
1 to 112 if the reference is a long Mode S (decimal ASCII)
1 to 56 if the reference is a short Mode S (decimal ASCII)
Example:
:ATC:DO260:TYPE:PREA:CHIPS:NFIRST 1\r
Default:
0
Query:
:ATC:DO260:TYPE:PREA:CHIPS:NFIRST?\r
Return:
1
