Screen Fields
The following input fields of the test parameters need to be specified for a new
test:
Input Field Description
Radio Standard
Select either GSM900, E-GSM, DCS1800, or PCS1900.
If Radio Standard is changed, Channel is also automatically
changed accordingly.
Channel
a
Specifies one traffic channel to be analyzed. The frequency
corresponding to the channel accompanies. The allowable range is
as follows:
GSM900: 1 to 124
E-GSM: 0 to 124, and 975 to 1023
DCS1800: 512 to 885
PCS1900: 512 to 810
Measurement
Range
Specifies one measurement range as follows.
+39dBm: The maximum input level is +39 dBm.
+29dBm: The maximum input level is +29 dBm.
+19dBm: The maximum input level is +19 dBm.
+9dBm: The maximum input level is +9 dBm.
−3dBm: The maximum input level is −3dBm.
Span
Selects either 0 to 400 kHz or ±100 kHz as follows:
o 0-400: Sets the span to 0 to 400 kHz relative to the
channel frequency.
o ±100: Sets the span to ±100 kHz centered at the channel
frequency.
RBW
Selects either 10 kHz or 30 kHz resolution bandwidth as follows:
o 10: Sets the resolution bandwidth to 10 kHz.
o 30: Sets the resolution bandwidth to 30 kHz.
Averaging
a
Specifies the averaging number of measurements from 2 to 99,
unless Off is selected.
DC Power
a
Selects a supply mode. The choices are On and Off as follows:
o On: Always supplies dc voltage to the mobile.
o Off: Disables to supply dc voltage to the mobile.
Accepts a dc voltage value ranging from 3.0 to 11.0 V in 0.1 V
steps. This value is used among the AUTOMATIC TEST,
MANUAL TEST, SPECTRUM MONITOR, and SIGNAL
GENERATOR modes in common.
