RIGOL DS1102D Mixed Signal Digital Oscilloscope Review (Part 2)


In the second part of overview we'll cover more details regarding RIGOL DS1102D Mixed Signal Digital Oscilloscope functions and menu.

RIGOL DS1102D Digital Oscilloscope

RIGOL DS1102D Dual-Channel Digital Oscilloscope Menu

The control over RIGOL DS1102D Digital Oscilloscope menu is provided using buttons and knobs. The menu is structured in two levels. User should get used to RIGOL DS1102D digital oscilloscope control as due to variety of options it takes some time to access some of them at first.

The MENU area of RIGOL DS1102D digital oscilloscope includes the following items:

  • Measure – auto measurements;
  • Cursor – cursor measurements;
  • Acquire – data recording;
  • Display – display;
  • Storage – data saving;
  • Utility – servicing.

Measure menu

Measure menu can display up to 20 parameters of signal auto measurements. 10 of them are voltage parameters and the other 10 are time parameters. Each of parameters except for the caption one is graphically represented for user convenient orientation.

Three parameters may be displayed simultaneously (bottom line). The next selected parameter appears on the right at the bottom, and the outside left one correspondingly disappears. All signal data may also be displayed by choosing the Display All menu item.

Measure menu

Cursor menu

Cursor menu allows conducting three types of signal detection:

  • Manual
  • Track
  • Auto Measure.

Tracking function result represents the voltage and signal time difference.

In the tracking mode channels for cursor (A) and cursor (B) are to be chosen separately. As a result we obtain data on any waveform point.

Cursor menu

For starting the automatic measuring mode a certain parameter from the Auto Measure menu should be chosen. For example, for a frequency parameter the period will be marked with a cursor and signal frequency will be determined.

Auto Measure

Acquire menu

Acquire menu allows adjusting the digital detecting system.

The first parameter of this menu is a data acquisition type (Normal Acquisition, Average Acquisition and Peak Detect Acquisition mode).

The second parameter is a real-time sample rate mode (Real Time) or equivalent sample rate mode (Equ-Time).

The third parameter is a memory selection: 512 K memory (dual channels) or 1 M (single channel) (Long Mem), 8 K memory (dual channels) or 16 K (single channel) (Normal).

  • Clearing all waveforms from the display.
  • Persistence (previous waveforms remain displayed on the screen until the persistence function is turned off).
  • Display contrast.

Utility menu

Utility menu provides the following settings:

  • Input/output configuration
  • Sound
  • Frequency counter
  • Menu language
  • Pass/Fail parameter
  • Waveform record
  • Printout
  • Settings
  • Auto calibration
  • System info

Tolerance test function Pass/Fail is one of the special functions of RIGOL oscilloscopes. On running this function RIGOL DS1102D digital oscilloscope automatically compares the input signal with a previously created signal form mask. If the signal form overruns the mask limits, the test result is Fail. Otherwise the test is passed. An audio alarm may be switched on in the settings, it will notify about the signal overrunning the mask limits. In the display left upper corner the amount of tested forms is shown: total, valid and faulty form numbers. A mode for this function may be set in the way that if signal overruns the mask limits the counting either will be continued (faulty forms will be counted) or stop right after the faulty signal form is detected.

Three modes with their settings are available in Storage menu:

Save mode

  • recorded signal source setup (CH1, CH2, Pass/Fail-OUT);
  • frame number setup (1000 max);
  • signal detection interval setup (1 ms – 1000 s).

Load mode

  • frame interval setup;
  • first frame setup;
  • last frame setup.

Memory import/export mode

  • first frame setup;
  • last frame setup;
  • memory select (internal/external).

The following menus are located separately:

  • Channel menu (CH1, CH2);
  • Mathematical operations menu (MATH);
  • Reference signal menu (REF);
  • Trigger menu (TRIGGER).

CH1 and CH2 Channel menu

In channel menu (CH1, CH2) the following settings may be adjusted:

  • channel communication type according to the current (AC, DC, GND);
  • bandwidth (on/off);
  • divider (1x – 1000x);
  • digital filter parameters (LPF, HPF, band-pass filter, ejector filter);
  • Volt/div (accurate/rough);
  • signal inversion.

Math menu

Math menu provides four mathematical functions:

  • Adding (A+B)
  • Subtraction (A-B)
  • Multiplication (A×B)
  • Fast Fourier transform (FFT)

A few words about the fast Fourier transform

Fast Fourier transform (FT) is based on a very simple, though exceptionally fruitful idea – almost any periodic function may be presented as a sum of separate harmonic components (sinusoid and cosine curve with different amplitudes F, periods T and, consequently, frequencies ω).

The indisputable FT advantage is its flexibility – the transform may be used for both continuous time functions, and for discrete ones. In the latter case it is called the discrete Fourier transform – DFT.

Executing the DFT of the input sequence directly – strictly following the initial formula, will require a lot of time (especially if there is a large number of input indications). It is more constructive to use divide and rule principle laying in the basis of the DFT algorithm. According to it the input sequence is divided into groups (e.g. even and odd counts), and the DFT is conducted for each of them, and then the obtained results are merged. As a result we have an input sequence DFT, and a significant time saving. That is why the described algorithm was named the fast Fourier transform.

REF menu

REF menu – using the reference signal

Reference waveforms are the waveforms which are stored in the memory and may be displayed. Reference signal function is available after saving the selected waveform into the nonvolatile memory.

HORIZONTAL zone menu

The following parameters are set in the horizontal time base menu:

  • Fragment increase mode (on/off)
  • Display mode selection (Y-T, X-Y, Roll)

Y-T – displaying the dependence of the voltage (Y axis) from time (X axis).

X-Y – displaying the dependence of CH2 value on the Y axis from the CH1 value on the X axis. This format is useful for investigating the phase relation of two signals.

Roll – auto recorder mode, when the waveform is refreshed on the screen from the right to the left.

TRIGGER zone menu

Trigger system sets the reference time of the data detection and signal form displaying by digital oscilloscope. The correct trigger system setup ensures fine waveform displaying and stable signal form displaying. Until the trigger moment the oscilloscope continuously records and saves a certain data amount enough for signal form displaying to the left from the trigger point. After trigger conditions execution the oscilloscope continues recording and saving the data for signal form displaying to the right from the trigger point.

TRIGGER zone includes one knob and three buttons:

  • LEVEL knob – a knob setting the trigger level, pressing its handle leads to setting a zero trigger level.
  • 50% button – special button with a single function, pressing which leads to setting the trigger level to the middle point of trigger signal vertical swing.
  • FORCE button – special button leading to the forced triggering, i.e. the oscilloscope takes it as fulfillment of trigger conditions. It is used mainly for oscilloscope setup under the normal and one-shot trigger modes.
  • MENU button – a button for displaying the trigger system control menu.

Trigger modes

RIGOL DS1102D dual-channel digital oscilloscope provides 7 trigger modes:

  • Edge: triggering by edge occurs when the input signal crosses the selected voltage level in the selected direction (rise, fall of random edge).
  • Pulse: triggering by pulse duration; this trigger mode is used to detect pulses of certain duration.
  • Video: triggering by video signal is used for triggering by fields or lines from line-synchronizing pulse of the standard video signals. It is worth mentioning about the video signal polarity mode, even and odd half-frame selection for frame synchronization.
  • Slope: triggering by the rate of rise is conducted by oscilloscope on executing the set conditions on duration and on the level of the rising (falling) signal edge. Such a solution is used in the oscilloscopes of this price range for the first time.
  • Alternate: by turn triggering from CH1 and CH2 channels for simultaneous observation of two nonsynchronized signals.
  • Pattern: triggering by certain logic signal pattern.
  • Duration: triggering by matching with certain logic signal pattern during a set time interval.
