A4 Function Selector board 2 45 The Time Base circuit has two modes of operation consistent with the two types of measurements performed by the 5328A For frequency and time interval type measurements the Time Base circuit generates gate during which either oscillator input pulses are counted For totalize type measurements the Time Base circuit divides its input by N as set on the RESOLUTION N switch on the front panel and outputs the divided signal to be counted in the 2 6 Model 5328A Theory of Operation yt DCA The outputs of the Time Base circuit corresponding to both operating modes are gener ated simultaneously Regardless of the type of measurement being performed these outputs are made available to the A4 Function Selector which selects the proper signal to perform the function 2 46 The length of the gate time generated by the Time Base circuit and the scale factor of the Time Base Input is determined by the Time Base code The 5328A Mainframe ROM reads the codes of both the Time Base RESOLUTION N and FUNCTION switches and outputs the proper code to the Time Base such that measurement resolution and scale factor agree with the infor mation in the various RESOLUTION N switch positions 2 47 A2POWER SUPPLY 2 48 The power supply shown in Figures 6 7 and 6 8 has five output voltages 5 5 2 15 15 and 3 5 volts dc The 5V and 5 2 circuits are essentially the same as are the 15 and 15V sect

F converter a conversion factor of 10 kHz volt is maintained regardless of the DVM s range The voltmeter may be placed in autorange and the user simply programs the DVM function from the Hewlett Packard Interface Bus HP IB and any voltage from 10 uV to 1000V is measurable 2 25 This technique results in a small problem If for example the user puts 900 volts on the input terminals the output frequency is 900 x 10 kHz 9 MHz In a measurement time of 1 2 4 Model 5328A Theory of Operation second this would provide resolution of 1 part in 9x 106 far beyond the resolution limit of the V to F converter To prevent the user from misinterpreting his results the module blanks the meaningless data thus providing the user with a display that contains only accurate data 2 26 Inthe measurement of trigger levels the high performance DVM performs much like the low cost version with an important exception Measurement of trigger levels normally requires the user to compensate mentally for the attenuation factor used in the universal module input attenuator For example if one volt is the trigger level voltage x1 attenuation yields an effective trigger level of one volt x10 attenuation yields 10 volts and x100 attenuation yields 100 volts The high performance DVM in combination with the high performance universal module eliminates the need for mental multiplication automatically reading out the effective trigger level in t
