1. MT8820A GPIB control procedure
This chapter indicates common GPIB procedures of the MT8820A and covers all
measurement software.
1.1 Basic sequence
The MT8820A is able to measure both TX and RX test items at once. Therefore, basic
measurement flow should be 1)parameter settings, 2)measurement, 3)result reading, as shown
in Fig.1-1 below. Most of the auto test software consists of a combination of this flow.
The following points must be noted when reducing the time of a measurement sequence:
• Settings of measurement items and parameters should be kept to minimum. (Do not
perform unnecessary settings.)
• Items should be measured as collectively and simultaneously as possible. (TX
measurement and RX measurement)
• Do not read any items not being measured or unnecessary results in measurement
result readings.
NOTE:The“SWP” command stops remote control temporarily until the measurement ends. Refer to ”1.2
Measurement start and synchronization” for details.
