    3.1.1 Introduction to oscilloscope family The family consists of four analog general purpose oscilloscopes with model numbers PM3082, PM3084, PM3092 and PM3094. All instruments have four vertical channels. Differences between these models are the vertical bandwidth, the features of the vertical channels 3 and 4 and the presence of switcheable 50Q input impedance.
  • Page 41: Explanation Of Signal Names

    3 - 4 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 42: Block Diagram Description

    3 - 5 DESCRIPTIONS 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 43: Vertical Channels

    3 - 6 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 50£2 input impedance while the 100 MHz types do not have this feature. Another difference is between the 4 channel and the 2 + 2 channel versions.
  • Page 44: Triggering And Time Bases

    5.1 - 1 UNIT DESCRIPTIONS UNIT DESCRIPTIONS SIGNAL UNIT A1 5.1.1 Description A1 5.1.1.1 Introduction With the exception of the final stages, unit A1 incorporates the vertical channels, the triggering, the time bases and the intensity (Z) control. The unit A1 description is split into the following chapters: Input attenuators and calibrator.
  • Page 57 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 50ft termination resistor and AC/DC input coupling circuit.
  • Page 58 5.1 -3 UNIT DESCRIPTIONS 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 59 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 60 5.1 -5 UNIT DESCRIPTIONS 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 61 5.1 -6 UNIT DESCRIPTIONS The balanced output signals FNC1DPOO and FNC1DP01 at pin 9 and 10 can be used to provide signals for future instrument extensions such as a digital signal storage. This is present on all 4 channels. Biasing current for these outputs is provided via V1302, V1313 and R1307. The capacitor C1301 determines the cut-off frequency if the bandwidth limiter is active.
  • Page 62 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 63 5.1 -8 UNIT DESCRIPTIONS DLENO-HT (Data Latch ENable) and DLEN1-HT determine if D9001 or D9002 reacts on the SDA/SCL signals. The figure below indicates the relation between SDA and SCL. DATA LINE CHANGE ! STABLE: OF DATA • DATA VALID ALLOWED! Figure 5.12 Relation of serial bus signals SDA and SCL D9003 and D9004 have outputs that control a number of on/off functions in the preamplifier.
  • Page 64 5.1 -9 UNIT DESCRIPTIONS 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 65 5.1 - 10 UNIT DESCRIPTIONS Pin 7. The signal is high during field 1 and low during field 2. Field 1 and Field 2 together form one frame. 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.
  • Page 66 1 - 11 UNIT DESCRIPTIONS D8004 has inputs and outputs with the following functions: TBEOHO-LX goes low at the end of the hold-off period. TBAUTO-LD is low if auto free run mode is active. TBEOM-HX goes high at the end of the MTB sweep. TBSTD-LX goes low to start the DTB sweep.
  • Page 67 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. The timing capacitance consists of C6011 that is always in circuit and C6012, C6013 that are activated via the switching transistors V6016 and V6019.

  • Page 363 5.6-2 UNIT DESCRIPTIONS To reduce the switching losses in V1019, a dV/dt limiter, often called “snubber", is used. C1021 decreases the dV/dt of the collector voltage of V1019 during switching off, as the current to the transistor can pass during a certain time through C1021. This slowing down of the collector voltage will reduce the switching losses during switching off.
