1. Input the PTE command "StartCall"
2. Input the PTE command "Receivecall".
3. Wait to indicate "Active" to establish call
1. ARFCN is assign to Mch ( and Lch/Hch )
2. Set PL to 5(E-GSM) or 0(DCS1800)
3. Wait to establish hand over
4. Measure output power
1. ARFCN is assigned to Mch ( or Lch/Hch )
2. Set PL to 5(E-GSM) or 0(DCS1800)
3. Wait to establish hand over
4. Change mode of GSM tester to "Phase/FREQ"
5. Set analyze burst number to 50
6. Read "RMS maximum" window
1. ARFCN is assigned to Mch ( or Lch/Hch )

4. Change mode of GSM tester to "Power Ramp"
5. To check pass/fail indication under three mode "TOP
2dB" "Rise edge" and "Fall edge"
1. ARFCN is assigned to Mch*1
2. Set PL to 5(E-GSM) or 0(DCS1800)
3. Wait to establish hand over
4. Change mode of GSM tester to "Bit error"
5. To define sampling value to 10000
6. To define measure "Res Type 2"
7. To adjust base station output level to -103.5dBm
8. Wait to indicate BE Ratio and read it.
1. Same setting and procedure as RX RBER
2. Wait to indicate "Mobile reported Rxlev" and read it.
1. Same setting and procedure as RX RBER
2. Wait to indicate "Mobile reported RX Qual" and read it.
1. Change mode of GSM tester to "DUAL BAND"
2. To define DCS1800 parameter. ARFCN to Mch, Base
