5 Screen Reference
The following measurement items are displayed in groups in the
table. When a group of measurement items is selected with the
CURSOR CONTROL knob, the Graph/Value screen for the group
is displayed.
Modulation
Selects one of the following modulation modes:
•
GMSK:BCCH: Sets the data of BCCH during call connecting.
• GMSK:PN9: Modulates RF signal in GMSK modulation and outputs with a 9-step pseudorandom
binary sequence noise.
• GMSK:PN15: Modulates RF signal in GMSK modulation and outputs with a 15-step pseudorandom
binary sequence noise.
• GMSK:All0: Modulates RF signal in GMSK modulation and outputs with all-zero data.
• GMSK:All1: Modulates RF signal in GMSK modulation and outputs with all-one data.
• 8PSK:PN9: Modulates RF signal in 8PSK modulation and outputs with 9-step pseudorandom binary
sequence noise.
• 8PSK:PN15: Modulates RF signal in 8PSK modulation and outputs with 15-step pseudorandom binary
sequence noise.
• AM: Applies AM modulation to carrier.
Offset Sets frequency offset of the output signal. The allowable range is -100.0 to +100.0 kHz in 0.1 kHz
resolution.
PWR CNTL Sets one of the factors defined for Power Control Levels according to the Radio System. The allowable
range is as follows:
GSM850, GSM900: 2 to 19 (+39dBm to +5dBm)
DCS1800: 29 to 15 (+36dBm to 0dBm)
PCS1900: 30 to 15 (+33dBm to 0dBm)
Set the MS Power Class on the [Configuration: Test Condition] screen for the power class of the mobile
phone. If the mobile phone does not support the power control function, measurement result is not
displayed.
Amplitude Sets the RF output level of the Signal Generator. The allowable range is from -110.0 to -20.0 dBm
in 0.1 dB steps.
Midamble
†
Sets the Training Sequence Code (TSC) to 0 to 7, or None for the amplitude triggering.
Demod Sets the modulation form of the MS signal.
Selects GMSK or 8PSK.
Installation of Option G03 is required for 8PSK
Averaging Displays the average value of Peak TX Power, Phase Error, and Frequency Error. Sets the averaging
number from 2 to 200, or Off. When this function is not required, select Off.
* The changing magnification softkey is available. Refer to Storing Numeric Values on page 8 and Changing Magnification Softkey on
page 13.
†When
None is selected, Phase Error/ Frequency Error cannot be measured.
