TEST_08 TX ORFS Due to Ramping
TEST_08 TX ORFS Due to Ramping
NOTE This test does not run on an HP/Agilent 8922 without a Spectrum
Analyzer Option 006.
Description This test measures the mobile station’s out-of-channel power due to
ramping (the rising and falling of the pulsed carrier).
The TX ORFS ramping offsets parameter selects which frequency
offsets will be measured.
The test is performed at the power control level specified by parameter
number 49 TX Power Control Level for TEST_08 (see page 162
for details).
The HP/Agilent 8922 makes Output RF Spectrum (ORFS)
measurements using a 3-pole synchronously tuned measurement filter.
Refer to the technical reference sheet Output RF Spectrum
Measurements Using a 3-Pole Synchronously Tuned Measurement Filter
(Agilent part number 1000-1223) available from the nearest Regional
Sales and Service Office.
The GSM 11.10, GSM 11.10 DCS, and PN 3389 recommendations
specify what the power levels should be relative to peak TX power at
the following frequency offsets:
• Spec 13 (
± 400 kHz)
• Spec 14 (
± 600 kHz)
• Spec 15 (
± 1200 kHz)
• Spec 16 (
± 1600 kHz)
NOTE The specifications for ORFS due to Modulation do not allow for the
exceptions in GSM 11.10 DCS II.3.4.2.2 for several discrete failures of
up to −36dBm at various points in the band.
NOTE Offsets greater than 1200kHz are not measured.
