Radio
The Radio key accesses a menu to select:
•
Band - Select the GSM band (P-GSM, E-GSM, R-GSM, GSM 450,
GSM 480, GSM 850, DCS 1800, or PCS 1900). Refer to the table in
the previous section for GSM band data.
•
Device - Select the device to test BTS (Base Transceiver Station) or
MS (Mobile Station).
• BTS Type - Select the type of BTS (Base Transceiver Station) to be
tested (Normal, Micro, or Pico).
• Freq Hopping - Turn frequency hopping on or off. If frequency
hopping is turned on, the instrument will ignore the bursts when the
frequency is hopped off the selected channel frequency. Thus only
valid data is included in the results. Only the Power vs. Time, and
the Phase and Frequency Error measurements can be made on
hopping GSM signals.
•
Carrier - Select the type of carrier to measure (Burst or Continuous).
