cr''lf']

Where: tttttttt = Equipment type.

xxx.yyy.zzz = Software version.


Equipment type specifies the unit and current firmware
versions.

Firmware
Information

Command:
Response:

<1/FI_'cr'
>1/FI_'cr'
VER_xxx.yyy.zzz'cr'
MC_FW/nnnnnn-ddr'cr'
MC_mm/dd/yy'cr'
FPGA_FW/nnnnnn-ddr'cr'
FPGA_mm/dd/yy'cr'
DSP_FW/nnnnnn-ddr'cr'
DSP_mm/dd/yy'cr''lf']

Where:


xxx.yyy.zzz = Software version number (0.0.0 to
999.999.999).

nnnnnn = Firmware number (0 to 999999).

dd = Firmware dash number (0 to 99).

r = Firmware revision (-, or A to Z).

Raw BER
Status

Command:
Response:

<1/RBER_'cr'
>1/RBER_xm.mE-ee'cr''lf']

Where:

x = < or > (data modifier to indicate that the E

b

/N

0

is less

than or greater than the returned value).

m.m = 1.0 to 9.9 (error rate mantissa).

ee = 1 to 99 (error rate exponent).


Reports current measurement of the raw BER.

Notes:

1. The 'x' parameter is only returned if the error rate has

exceeded the computational resolution of the system.

2. 'No Data' is returned if the error rate cannot be

calculated.

3. 'Sampling' is returned if not enough data is currently

available to calculate the error rate.

Corrected
BER

Command:
Response:

<1/CBER_'cr'
>1/CBER_xm.mE-ee'cr''lf']

Where:

x = < or > (data modifier to indicate that the E

b

/N

0

is less

than or greater than the returned value).

m.m = 1.0 to 9.9 (error rate mantissa).

ee = 1 to 99 (error rate exponent).


Reports current measurement of the corrected BER.

Notes:

1. The 'x' parameter is only returned if the error rate has

exceeded the computational resolution of the system.

2. 'No Data' is returned if the error rate cannot be

calculated.

3. 'Sampling' is returned if not enough data is currently

available to calculate the error rate.
