Y-1 amplifier

The simplest and cheapest Y amplifier. It provides a "oscilloscopic" input resistance, or 1Mohm (the possibility of cooperation with a typical oscilloscope probe) and a bandwidth of several MHz. It can also work as a simple 50 ohm input of a broadband oscilloscope (then full bandwidth, but without amplification).


Y-2 amplifier

Actually a broadband repeater. Rwe = 1Mohm, and full bandwidth of the Y amplifier (200 ... 300MHz), but without amplification.


Y-3 amplifier

Bandwidth around 100MHz at the lowest sensitivity; as the gain increases, the frequency band decreases proportionally.


Y-4 amplifier

The full version of the Y amplifier. 200 ... 300MHz band, 1: 1 attenuators, 1:10, broadband amplifier.


Time measurement module T-1

Thanks to this module, a simple real-time oscilloscope turns into a widescreen oscilloscope with random sampling. Only with this module it is possible to obtain fast time bases - up to approx. 1ns / div.


PS-1 power supply

Power supply for the analogue part +/- 15V, power supply to the digital part + 5V, + 3.3V.



The estimated prices of different versions of the modular oscilloscope would be as follows:

  - basic module ADCC-1 ("heart" of the oscilloscope):   approx. EUR 1000

  - the simplest version (basic module, the simplest Y-1 amplifier, the simplest TRIG-1 challenge system):   approx. EUR 1800

  - one-channel full version (basic module, Y-4 amplifier, TRIG-3 triggering system, T-1 timing module):         approx.  EUR 6500

  - two-channel full version (basic module, two Y-4 amplifiers, TRIG-3 triggering system, T-1 timing module):   approx. EUR 8000

Widebandwidth low-cost oscilloscope 


The AB-LAB engineers have several self-developed and running oscilloscopes behind them. These were experimental devices, and the studies were of more research than production character. Nevertheless, we can do oscilloscopes!

Now we want to create a product for sale. We are planning to produce a relatively cheap modular oscilloscope with good performance and modular design.

The modular structure will enable the user to decide independently what parameters his device should have; if you want to develop some modules yourself or buy ones. If the finished modules will be few and they will be in the simplest versions, the price of the entire device can be very low. Depending on the complexity of the modular oscilloscope, the price can range from about EUR 1000 to about EUR 8000. More detailed calculations later in the text.

We want the system to have open control and display software that users could modify and write themselves.The set of modules to be developed will allow for a wide range of device options: from a simple data recorder with a bandwidth of a few MHz, to an oscilloscope with a bandwidth of over 200 MHz with a trigger with a similar frequency range.


The full version of the modular oscilloscope will be based on the idea of Random Repetitive Sampling (RRS).


The RRS technology was introduced in the eighties by one of the leading oscilloscope companies. Although this technique does not allow to visualize unique waveforms (only Real-time oscilloscopes can do this), the vast majority of waveforms are repetitive. It is worth noting that the Real-time technique is true of the idea the most obvious method of collecting information about the signal, but with larger bands it is much more expensive than other oscilloscope techniques.


Modular oscilloscope - assumed parameters:

(complete set - all modules with the best parameters):

- frequency band of the Y track: 0 - 200 MHz (at least)

- track sensitivity Y: 20mV / div (maybe there will be 10mV / div)

- sample record: 1kS to 10kS, 8-bits

- trigger frequency range: 0 - 400MHz

- time bases 1s / div - 1ns / div





ADCC-1 basic Y path module ("heart" of the oscilloscope)

The basic module is an 8-bit DAC with a sampling rate of 20MS / s, an ARM processor collecting these samples and a 20MHz clock.The basic module itself is a simple Real-time data recorder with quite small possibilities - there is no trigger, theoretically 10MHz band, practically on the order of 2MHz.


Basic module AD YCC-2 two-channel version

Basic module with added second ADC converter; other data as above


The second channel

A second, complementary DAC converter that collects the second set of data.


Trig-1 trigger system

The simplest version of the trigger system. Only useful if the user is satisfied with a few MHz bandwidth


Trig-2 trigger system

An intermediate version of the trigger module. Bandwidth - around 80MHz. Useful if the user will need a larger Y-band, but will not have to watch very high frequency signals.


Trig-3 trigger system

Full release version - working up to approx. 400MHz.

Unfortunately, expensive- special, unusual elements are needed.
