149. 400 usec and to overcome a rather large inductance of the deflection coil a boost voltage is applied to the output amplifier power supply rail This larger voltage allows the current in the yoke winding to change rapidly Once the retrace is complete the supply rail returns to the normal voltage 21 V to conserve power in the output amplifier At the same time the Ramp generator TDS 520B Mod CM Component Service Manual Detailed Circuit Description portion of the IC has returned to the starting point of the ramp and will produce a voltage ramp at the rate set by the R C timing components until another sync signal occurs in the absence of sync the generator will reset itself at a predetermined level and the scan will free run at a slightly lower frequency An external component network modifies the ramp shape resulting in a scan waveform which will produce a linear movement of the CRT beam across the face ofthe CRT This correction causes the resulting ramp of voltage to acquire a slight 5 shape hence the majority of the correction is called 5 correction The center of the S may be moved about by the linearity adjustment to accommodate non uniformity of the deflection coil and other coil losses The modified ramp is fed to the input of the output amplifier This voltage is applied against a negative feedback signal which results from the deflection coil current flowing in a small current sampling
150. 48 bit instruction word Buffers U1084 and U1083B buffer the DSP s read and write signals to its three buses When BUSGRANT goes high the outputs enter their high impedance state so that the 68020 can use the DSP s buses Table 1 13 lists the memory map for the DSP Memory In general the acquisition system uses the D1 Memory The buffers and latches buffer and demultiplex the X bus from the DSP to create the D1 bus When the bus is granted to the 68020 BUSGRANT is high the outputs of the buffers and latches enter their high impedance state In general the display system uses the D2 Memory The buffers and latches buffer and demultiplex the Y bus from the DSP to create the D2 bus When the bus is granted to the 68020 BUSGRANT is high the outputs of the buffers and latches enter their high impedance state D2MMIO Decoding decodes the address space and generates chip selects for all registers on the All DRAM Processor Display board accessible by the DSP The DSP D2MMIO Misc Register inside U2111 controls 68020 interrupts and tells both the DSP and the 68020 whether or not the FIFO is full Table 1 14 describes the contents the D2MMIO Misc Register The DSP performs tasks as directed by the 68020 processor and reports results back either through interrupts or by using the FIFO U1074 The DSP can pass data back to the 68020 through the FIFO without having to halt DSP processing Interrupt FIFOINT to the 68020 is generated when
151. 5 4 CH2 is fed into IN2 H L pin 41 41 The main trigger output is OUT11 H L pins 20 21 and the delay trigger output is OUT21 H L pins 26 25 The channel switch allows either Ch1 or Ch2 to be the main or delay trigger event or both The comparators are after the channel switch so the trigger level and hysteresis controls are associated with the main delay trigger rather than Ch1 or Ch2 trigger Trigger coupling is generated with U1560 U1561 filter circuits Referring to Chl AC coupled trigger occurs when C1556 is connected to ground via U1556 and the analog trigger 01551 is programmed to subtract this filter output from the Chl trigger input signal LF reject is achieved similarly except C1556 is disconnected from ground HF reject is like LF reject except that rather than subtracting the CP1 input signal pin 7 from the Chl trigger signal the input signal itself is used as the input Noise reject is done by increasing the trigger hysteresis via those analog control voltages pins 11 and 35 for main and delay hysteresis respectively U1552 does the same thing for Ch3 and Ch4 The EVNT 1 4 outputs from U1551 and U1552 are fed to the trigger logic IC U1001 sheet 20 The trigger logic chooses between Ch1 2 and Ch3 4 for main and delay trigger events U1551 91552 contain built in shift registers for programming of the channel switch and coupling modes The serial data SDATA comes from U1050 TDS 520B Mod CM Component

ID version identification circuitry Flash ROM All oscilloscope makes use of flash memories for its Flash ROM This allows lt gt the Flash ROM to be programmed while it is in the oscilloscope With 12 V supplied to the Firmface the Flash ROM can be programmed via programs running in Kernel RAM programs which are downloaded via the GPIB Flash Fundamentals Programming Flash ROM involves three steps In step one if the Flash ROM is not fully erased erased byte FF then it is programmed to the zero state In step two 1f step one was necessary every cell is erased to the one state Step three sequentially programs each long word with the desired data Only those cells that are zero bits are programmed Bits that are ones are simply left alone in the erase state Writes to the Flash ROM are possible only when 12 V is supplied The All DRAM Processor Display board has a switch S1002 that turns this program ming voltage on and off Switch forward programming voltage on This switch should only be toggled forward or back as directed by the firmware update program The program queries the All DRAM Processor Display board and the Firmface board for their ID numbers so it can determine how to configure registers on the A11 DRAM Processor Display board and how to program the DRAM Controller to enable the DRAM Front Panel A12 The front panel is the operator s interface for controlling the user selectable scope f
