The software for making attenuation program is a standard accessory 3. GP-IB ��nd RS-232C are equipped as standard accessories 4. Four models are prepared for every frequency band *model A : 1.5 to 4.5GHz *model B : 3.0 to 9.0GHz *model C : 4.5 to 13.5GHz *model D : 1.95 to 5.85GHz 5. The maximum attenuation is 80dB 6. The minimum step size of attenuation is 0.05dB

��Setting of attenuation
Two methods are available for setup of attenuation ; manual or program. Select one by "ATTEN MODE".��Manual modeSet the attenuation using the rotary encoder on the front panel. Alternatively, perform setup from outside using RS-232C or GP-IB. The setup parameters in manual mode are attenuation ��nd filter only.
M A N U A L 2 3 . 4 5 d B 3 0 μ s
��Program modeRead the memory storing attenuation data transferred from the computer. There are five parameters in the program mode ; readout clock, program length, hold-off period, readout mode ��nd filter.
P R G M 1 0 k H z L : 1 3 1 0 7 2 P : 6 . 5 5 3 5 s F R E E 3 0 μ s
The program readout period is the period from address 0 of the memory to address n ��set by program length��. The program length can be set between 8 ��nd 131072 words in one word step. When the program is read up to address n, the attenuation data at address n is held for the hold off period ��set by number of readout clocks or by time��, ��nd on termination of hold off period, the memory is read out from address 0 again.
About a filterCR filter is inserted in the attenuation controlling line. Use when it is required to smooth the change at the moment of switching attenuation. However, it is necessary to pay attention to the relation with the readout clock. An appropriate filter value is normally 1 / 2 to 1 / 8 of the clock period.
��The method of a programWhen it is necessary to use the program mode, input the program ��waveform�� on a Windows computer using "Software for making attenuation program", which is provided as a standard accessory. Then transfer this attenuation data to the memory of MAT800 using RS-232C or GP-IB. Readout clock, program length, hold off period, readout mode ��nd filter are set from the computer. Of course it is possible to set by keys on the front panel. Connect external clock ��nd trigger signal as required.�� Waveform creation1. Standard waveforms inputThe nine types of standard waveforms are prepared. They are sine wave, triangle wave, square wave, ramp wave, sinX / X, ��1-ε-ax��, ε-ax white noise ��nd DC.2. Straight line inputTwo specified points are linked together by means of a straight line.3. Arithmetic calculation inputA waveform is created by arithmetic calculation of addition, subtraction, clipping, absolute, mirror, smoothing, resize ��nd offset.4. One-point inputA waveform is created through input of one point at a time.
�� Waveform editing ��nd file managementWaveform editing ��nd file management may be performed using CUT, COPY, PASTE ��nd UNDO��Program readout mode
Three program readout modes are available ; Free, Burst ��nd Gate. Readout is executed regardless of the trigger signal in the Free mode. In the Burst mode, the readout of program memory is started at the rising edge of the trigger signal, the attenuation data of the terminating address is held until the next activation. Therefore, setup of the hold off period is not permitted in the Burst mode. In the Gate mode, one set of the readout of program memory ��nd hold off period is repeated while the trigger signal is of a high level. The last attenuation data is held when the trigger signal goes down to a low level ��nd then address n of program memory is read out. With wireless communication equipments, W-CDMA, CDMA, GSM, PDC, PHS, ETC, wireless LAN ��nd Bluetooth, the transmission power changes due to obstacles ��nd multi-paths besides theoretical space losses, when the radio wave is transmitted through the space. This changing pattern can be simulated using MAT800 ��nd the communication quality can be evaluated. This changing pattern can be easily created using "Software for making attenuation program". It will be very convenient if our "Shielding box ME8661A" is used for this test.
