GPIB control? ?

TDMA measurement hardware (MT8820A-02) Batch readout command for measured results The MT8820A-02 TDMA measurement hardware can measure the main test items of transmission and reception characteristics for GSM/GPRS that is most spread in the world in combination with MX882001A GSM Measurement Software. The combined use of MX882001A-11 EGPRS Measurement Software enables the measurement of main Tx and Rx characteristics on EG- PRS, which is the high-speed version of GPRS. And this option can measure the major transmission/reception char- acteristics on the second-generation PDC (PHS) system, the most common terminal in Japan, in combination with the MX882004A (MX882005A) PDC (PHS) Measurement Software. All results obtained by batch measurement can be read out with the single command: “ALLMEAS?”. If required, only desired measure- ment results can be read out using a command such as “ALL MEAS? MOD” (modulation analysis). A decrease in the number of GPIB commands reduces the GPIB traf- fic on both the MT8820A and control PC, contributing to the increase in measurement throughput. Since the step size of the control program is also reduced, this provides a real benefit to the user for the creation of a control program that is easy to read and maintain.

Options? ?

CDMA measurement hardware (MT8820A-03) This option can measure the major transmission/reception charac- teristics on the third-generation cdma2000 1X terminals conforming to 3GPP2, in combination with the MX882002A CDMA2000 Measurement Software. W-CDMA measurement hardware (MT8820A-01) The MT8820A-01 W-CDMA measurement hardware can measure the main test items of transmission and reception characteristics for 3G W-CDMA conforming to 3GPP in combination with MX882000B W-CDMA Measurement Software and MX88205xA W-CDMA call Process Software.

?

Audio board (MT8820A-11) The MX882000B-01 W-CDMA (MX882001A-01 GSM) Voice Codec is optional software that brings real-time voice encoding and decod- ing to the W-CDMA (GSM) Measurement Software. Installation of this and the MT8820A Option 11 (audio board) achieves end-to-end communication testing with handsets. In addition, the audio measur- ing function enables transmission/reception audio measurements to be performed while a call is connected.
