Cwejman RG-6 Random Generator


The RG-6 is Cwejman´s powerful module for generating various random signals. Available are three different stepped random voltages, a random gate, random clock and random sawtooths.

We currently do not accept pre-orders for Cwejman products. If you are interested in this module, please use the availability notification. The number of Cwejman circuits is limited. Therefore, we recommend you to order online IMMEDIATELY when a module becomes available. Enquiries via e-mail or telephone are usually not fast enough. (More detailed information can be found on the product page.)



The three outputs to the left produce, similar to a sample & hold, stepped random voltages with random probabilities of the spread. The internal clock generator is used here as well as an internal noise signal which acts as a sample source for the S&H. Instead of the noise you can apply an external sampling signal. It can be coltrolled in level what will affect the random voltages. The voltage controllable parameter SLEW smoothes the stepped voltages.

The clock can be tapped at an individual output.

Two outputs carry a random sawtooth signal - the first output is phase inverted, the second output has positive polarity. The coltage controlled parameter Slowe affects the level and polarity of the sawtooths. The positive sawtooth output is normalized to the clock rate CV input and allows for a easy to create random clock.

Random gate signals are generated, depending on the state of the random sawtooth. The sawtooth´s level is being analysed and when exceeding a adjustable threshold a gate signal with controlable length is produced. Both parameters, threshold and length are voltage controllable.

All Cwejman modules are screened against interferences, protected against reverse polarity and contain calibration options on the backside. (See photograph.)

Attention: Unlike other manufacturers, the red stripe of Cwejman's flat ribbon cable indicates the positive +12 V rail, not the negative one!


We currently do not accept pre-orders for Cwejman modules. For some products, there are waiting lists with pre-orders from the years 2013 to 2017, which are being processed as a matter of priority.
If you’d like to be informed as soon as this module is back in stock, please activate the availability notification via e-mail.
Please note: The number of Cwejman modules is always limited and much lower than the number of interested parties. Therefore, we recommend to order IMMEDIATELY and ONLINE if a Cwejman product becomes available. Enquiries via e-mail or telephone are usually not fast enough.
If the demand is higher than the supply, unfulfillable pre-orders will be deleted. In this case you’ll receive an e-mail. (Pre-orders on the waiting lists mentioned above are excluded from this policy.)
