Chapter 1 - UUT Measurement Return Data
1.1 INTRODUCTION
This chapter contains general information about dPMR UUT Measurement return data.
Refer to the 3900 Series Digital Radio Test Set Remote Programming Manual for detailed
information about 3900 system remote commands.
1.2 UUT MEASUREMENT RETURN VALUES
The information returned in UUT Measurement Meters data strings varies depending on
the type of measurement. The following are examples:
<statusbyte>,<failbyte>,<avgcount>,<avg>,<wc>
<statusbyte>,<failbyte>,<precision>,<percentage>,<avg>,<max>,<min>,<units>
<statusbyte>, <failbyte>, <avgcount>, <avg>, <max>, <min>
1.2.1 Status Byte (Bitmask)
Status Byte returned in the following bit position indicates measurement reading status:
Bit 0 = Invalid
Bit 1 = Inaccurate
Bit 2 = Settling
Bit 3 = Squelch
Returns 0 when measurement reading is valid.
1.2.2 Fail Byte (Bitmask)
Returns 0 in the following bit position when limit check has passed.
Returns 1 in the following bit position when limit check has failed.
Bit 0 = Minimum Upper Limit
Bit 1 = Minimum Lower Limit
Bit 2 = Maximum Upper Limit
Bit 3 = Maximum Lower Limit
Bit 4 = Average Upper Limit
Bit 5 = Average Lower Limit
Bit 6 = Worst Case Upper Limit
Bit 7 = Worst Case Lower Limit
Upper range value of 2.71 GHz is only valid for some 3900
models/options. Refer to product specifications for valid upper
range.
Statusbyte may return more than one condition as a bitmask.
Failbyte may return more than one condition as a bitmask.
