(4) Analog receiver measurement
The MT8801C sends an analog modulated test signal to an analog receiver
(DUT), and the demodulated signal (AF signal) from the receiver is input to the
MT8801C. Then the MT8801C measures the following items:
• Demodulated signal (AF) level
• Demodulated signal (AF) SINAD value
• Demodulated signal (AF) distortion
• Demodulated signal (AF) frequency
(5) AF signal measurement
The MT8801C sends an AF signal from the AF Output connector to a DUT, and
an AF signal from the DUT is input to the AF Input connector of the MT8801C.
Then the MT8801C measures the following items:
• AF input signal (AF Input) level
• AF input signal (AF Input) frequency
• AF input signal (AF Input) distortion
(6) Call processing
The MT8801C peforms the call-processing (location registration, origination,
termination, conversation, hand-off, mobile-station release, network release,
and others) sequence between the MT8801C and the DUT (mobile station).
The following functions are provided to these functions.
• Save/recall
In TX Measure mode, the measurement conditions (Parameters) and Gated
output power measurement templates (amplitude standard lines) can be saved
or recalled up to 100 types to/from an FD (3.5-inch floppy disk).
Also in RX Measure mode, set output patterns up to 100 types can be saved
and recalled through the FD.
• Copy
Outputs the image on LCD screen to an external printer using a parallel inter-
face (conforming to Centronics type).
• GPIB
The MT8801C can be controlled by an external controller using the GPIB
interface.
• RS232C
The MT8801C can be controlled by an external controller using a serial inter-
face (RS232C).
