DESCRIPTIONS 3 - 5 DESCRIPTIONS GENERAL DESCRIPTION 3.1.1 Introduction to oscilloscope family The family consists of seven digital general purpose oscilloscopes with model numbers PM3370B, PM3380B, PM3384B, PM3390B, and PM3394B. Differences between these models are the vertical bandwidth, the features of the vertical channels and the presence of switcheable 50Ω input impedance.
Page 54: Explanation Of Signal Names
3 - 6 DESCRIPTIONS 3.1.3 Explanation of signal names Throughout the circuit diagrams signal names are used. These names make it easier to trace a signal going from one circuit diagram to another. In many cases the signal name and also the component to which a certain node is connected are given in the circuit diagrams.
Page 55: Block Diagram Description
DESCRIPTIONS 3 - 7 Some important notes: To measure some signals, it is necessary to unlock units. Refer to chapter 8.5 for details on how to proceed. The given AC and DC signals are average values: your oscilloscope under test may deviate from the values given in the circuit diagrams.
Page 56: Vertical Channels
3 - 8 DESCRIPTIONS 3.2.2 Vertical channels There are 4 vertical channels that are mainly identical. A difference is that the 200 MHz oscilloscope versions have a switchable 50Ω input impedance while the 100 MHz and 60 MHztypes do not have this feature.
Page 57: Triggering And Time Bases
DESCRIPTIONS 3 - 9 3.2.3 Triggering and time bases The sections for Main Time Base (MTB) and Delayed Time Base (DTB) are for the greater part identical. Therefore the MTB part is extensively described and then the DTB part briefly. The EXTernal TRIGger input of the 2 channel versions is only different in the attenuator part, after that it is equal to and described as CH4.
Page 58: Final Amplifiers
3 - 10 DESCRIPTIONS An output signal from DTB TRIGGER FILTERS + AMPLIFIERS can be used for X DEFLection (MTB and DTB are off then) via the block TIME BASE / X DEFLECTION INPUT CIRCUIT. The function of DTB CURRENT SOURCE, DTB TIMING and DTB SAWTOOTH PICK OFF is identical to the corresponding blocks in the MTB section.
Page 59: Front Unit And Microprocessor
DESCRIPTIONS 3 - 11 Intensity and focusing. The FINAL Z INPUT STAGE receives input signal for trace intensity (ZS) from the Z CONTROL block in the time base section. A second input signal (ZD) determines the intensity (Z) component of the text information.
Page 60: Digitizer
3 - 12 DESCRIPTIONS The LINE IN voltage is applied to the LINE FILTER. This block prevents line interference from entering the supply unit. Also interference generated by the power supply does not enter the mains. An output signal of the filter is applied to the LINE TRIGGER PICK OFF in order to facilitate line triggering of the time bases.
Page 61 DESCRIPTIONS 3 - 13 3.2.7.1 Input stage Four input channel signals for channels 1, 2, 3, and 4 from the analog oscilloscope section are applied to the digitizer unit via eight coaxial cables. Each of these symmetrical input channel signals is splitted in two equal signals by a signal buffer and SPLITTER.
Page 62 3 - 14 DESCRIPTIONS With events selected, the trigger detection unit catches the first edge. With this edge it enables an event counter in the DATA ACQUISITION AND TRIGGER LOGIC. When it has finished counting the required number of events, a second stage in the trigger detection unit is enabled to catch the last event clock.
Page 63 DESCRIPTIONS 3 - 15 The SBUS (serial bus interface) is part of the DARLIC circuit. It is supporting a very limited number of capabilities. Its register is controlling two open collector I/O pins, SDA (serial data) and SCL (serial clock), and a select line SSEL. The buffer enables the DSP to read the status on the SDA and SCL lines.
Page 64 3 - 16 DESCRIPTIONS 3.2.7.8 Bus Arbiter and Trace Generator The major function of the BUS ARBITER AND TRACE GENERATOR (BATGE) is the arbitration between multiple processors, multiple memories and memory mapped I/O with a minimum of interference. Wait cycles for memory devices are programmable and active devices like the DARLIC circuit for example, generate a "not ready signal".

The unit A1 description is split into the following chapters: Input attenuators and calibrator.
Page 76 5.1 - 2 UNIT DESCRIPTIONS 5.1.1.2 Input attenuators and calibrator Diagram 1, 2, 3, 4 The attenuators of channels 1, 2, 3 and 4 are identical, therefore only channel 1 is explained. Every attenuator basically consists of four sections. These sections are: The input circuit with 50Ω...
Page 77 UNIT DESCRIPTIONS 5.1 - 3 The signal ATCAL is applied to /33 attenuator R1008/R1009. ATCAL can supply several accurate voltages that are used for vertical calibrations. Impedance converter This active stage consists of three sections with different frequency ranges. The sections partly make use of the same components: The HF section for frequencies above 5 kHz.
Page 78 5.1 - 4 UNIT DESCRIPTIONS Calibrator This circuit is used for probe adjustment. It is built up around triple analog multiplexer D1151. The sections D1151/1,2,10,15 and D1151/3,4,5,9 form a 2 kHz oscillator. The third section D1151/11,12,13,14 switches in the 2 kHz rate of the oscillator. The oscillation principle is now explained with the simplified diagram in the figure.
Page 79 UNIT DESCRIPTIONS 5.1 - 5 The amplifier D1201 can be switched to a number of attenuation/gain positions that are dependent on the channel 1 AMPL position. The gain x1 position is determined by R1205/R1206/C1205 that are present across pin 6 and 7. The x1 is switched by control signal PA1X1. The attenuation /2 is determined by R1207 and switched by PA1/2.
Page 80 5.1 - 6 UNIT DESCRIPTIONS The balanced output signals FNC1DPO0 and FNC1DPO1 at pin 9 and 10 can be used to provide signals for digital signal storage. The signals are routed via the coaxial sockets X1301 and X1302 to the sockets X8001 and X8002 on digitizer unit A8. This is present on all 4 channels. Biasing current for these outputs is provided via V1302, V1313 and R1307.
Page 81 UNIT DESCRIPTIONS 5.1 - 7 D5503 gives the necessary inversion of the main trigger path if channel 2 is in the inverted mode. The signal CNT4MTI-HT that is present at pin 4 of AND gate D5503 gives inversion of the main trigger path if channel 4 is in the inverted mode.

Page 83 UNIT DESCRIPTIONS 5.1 - 9 5.1.1.5 Main and delayed time base triggering Diagram 12 The main time base triggering (MTR) is mainly formed by IC D6541. The other IC D6621 is the peak- peak detector for the trigger level. The balanced input signal for triggering on vertical channels 1, 2, 3 or 4 is applied to pin 7 and 8.
Page 84 5.1 - 10 UNIT DESCRIPTIONS The set/reset flipflops D6779 make the field 1 (MTRTVFLD1) and field 2 (MTRTVFLD2) pulses. As input signals are used the output signals at pin 7 and 3 of N6771. The multiplexers D6781 and D7771 select the TV and line trigger sources for MTR and DTR: The MTB TV trigger signal is MTRTVSYNC.
Page 85 UNIT DESCRIPTIONS 5.1 - 11 TBNOTTR-HT goes high if the MTB is not triggered. TBSEL selects MTB if high and DTB if low. TBSSG-HT goes high at the end of a single sweep. DSOM (pin 2) goes high if a MTB trigger occurs. The connected circuit with V8023/8024 generates signal DSOMOUT that is routed via coax socket X8011 to socket X8503 on digitizer unit A8.
Page 86 5.1 - 12 UNIT DESCRIPTIONS Diagram 16 This diagram indicates the timing circuits for the MTB. The principle of the time base is that a capacitor is charged with a constant current. This gives a time-linear voltage across the capacitor; the so- called sawtooth or sweep signal.

Page 177: Final Xyz Amplifier A2
UNIT DESCRIPTIONS 5.2 - 1 FINAL XYZ AMPLIFIER A2 5.2.1 Description of A2-200 MHz version 5.2.1.1 Final Y amplifier Diagram 1 The output signal from the delay line is applied to the input pins 6 and 9 of amplifier IC D1001. Also the vertical output signals YTXT0 and YTXT1 from the digitizer unit A8 are applied to D1001 (pin 15 and 16).
Page 178 5.2 - 2 UNIT DESCRIPTIONS The other plate is driven by push-pull stage V1107/V1112. The driver transistors are V1101 and V1104. The input signal is YPREOUT0. The output voltage applied to the CRT deflection plates is controlled by the feedback networks R1101/R1141/R1143/C1101/V1113/R1140/C1121 and R1102/R1142/R1144/C1102/V1113/R1145/C1122.
Page 179 UNIT DESCRIPTIONS 5.2 - 3 The final X amplifier half that drives the left deflection plate is explained now. Its function is identical to that of the other amplifier half. The balanced input signals XDRIL1 and XDRIL0 are applied to input stage V2101.
Page 180 5.2 - 4 UNIT DESCRIPTIONS The intensity is influenced by the output signal INTEN-AA of the Z- amplifier and the signal INTEN- DA. INTEN-AA is determined via the front-panel INTENS TRACE, INTENS TEXT, MTBI and chopper blanking control signals. The HF component in the INTEN-AA signal is applied to G1 of the CRT via C4037.

UNIT DESCRIPTIONS 5.2 - 35 5.2.7 Description of A2-100 MHz version 5.2.7.1 Final Y amplifier Diagram 1 The output signal from the delay line is applied to the input pins 6 and 9 of amplifier IC D1001. This IC and surrounding components comprise the MF and HF square wave compensations. Also the vertical CRT text signal is applied to D1001 (pin 15 and 16).
Page 212 5.2 - 36 UNIT DESCRIPTIONS Diagram 2 This diagram shows the Y-output amplifier. The amplifier is located at the small printed circuit board at the CRT socket. The input signal is a current and is applied to V4101 and V4102. The output signal is voltage and is applied to the vertical deflection plates of the CRT.
Page 213 UNIT DESCRIPTIONS 5.2 - 37 Diagram 4 This diagram shows the final intensity (Z) and focusing amplifiers. These amplifiers drive the intensity electrode G1 and the focusing electrode G3 of the CRT. The input circuit is formed by IC D3001. Input pin 5 and 6 of D3001 receive the Z-pulses ZLTRA0 and ZLTRA1 that determine the intensity during signal display.
Page 214 5.2 - 38 UNIT DESCRIPTIONS The HF component from the focusing amplifier output signal FOCUS-AA is applied to G3 via C4004 and voltage divider R4008/R4009/C4002/C4003. This assures optimal tracking between focus and intensity. The signal FOCUS-DA is determined via the FOCUS control at the instruments front panel. The signal FOCUS-DA is then mixed with the LF component of FOCUS-AA before its level is adapted to the nominal G3 voltage via transistors V4002/V4003/V4004.
