Tx spurious emissions Test Case 3 (for three carriers)
Measurement method
Measures the active carrier power in a 1.23 MHz bandwidth, then
measures the power in a 30 kHz bandwidth at the adjacent and 1st
alternate offsets above and below the active carrier and measures the
power in a 1 MHz bandwidth at the 2nd alternate offsets above and
below the active carrier, displays the absolute power of the offset
powers in dBm
Measurement offsets

1st Alternate offsets
2nd Alternate offsets
±2.5 MHz
Settable from ±2.7 MHz to ±3.47 MHz, default of 3.47 MHz
Settable from ±3.5 MHz to ±6.5 MHz, default of ±6.5 MHz

Offsets
1.23 MHz
30 kHz synchronously tuned, five pole filter with approximately Gaussian
shape for the adjacent and 1st alternate offsets 1 MHz synchronously
tuned, five pole filter with approximately Gaussian shape for the 2nd
alternate offsets
Marker relative level accuracy
Adjacent offsets

2nd Alternate offsets
< ±1.3 dB, typically < ±0.65 dB
< ±1.4 dB, typically < ±0.75 dB
< ±1 dB, typically < ±0.6 dB
Measurement residual relative power

Mobile pass/fail limits (per C.S0033)
Auto mode
–– 2.5 MHz to 2.7 MHz
–– 2.7 MHz to 3.5 MHz
–– 3.5 MHz to 7.5 MHz
−14 dBm / 30 kHz
− [14 + 15 × (Δf – 2.7 MHz)] dBm / 30 kHz
− [13 + 1 × (Δf – 3.5 MHz)] dBm / 1 MHz
Manual mode
Settable from −10 to −65 dBc with 0.01 dB resolution
Numeric results
Absolute power in dBm/30 kHz for the adjacent and 1st alternate offset
frequencies and in dBm/1 MHz for the alternate offset frequencies

Amplitude range
Single trace with C.S0033 standard limit lines and one bar representing
the channel power and six bars representing the absolute power at the
six offset frequencies
