Review: Teledyne LeCroy WaveStation 2052 – Arbitrary Waveform Generator
After having a look at a Teledyne LeCroy WaveAce series oscilloscope recently, it’s time to have a look at the entry-level WaveStation family of arbitrary waveform generators. The WaveStation generators and the WaveAce oscilloscopes are designed to be capable of working hand-in-hand. The Teledyne LeCroy WaveStation 2052 is a 50 MHz, 2-channel Function/Arbitrary Waveform Generator […]

Review: Abracon ABFT Frequency Translators
In March, 2012, Abracon announced the production of ultra-low jitter, VCXO based frequency translators / jitter attenuators. This is supposed to resolve some problems that accompany classic PLL-based designs at an affordable price. Now, the ABFT frequency translators / jitter attenuators are available on the market and it’s time to have a closer look. The […]

Review: Abracon Sync’n Go – Portable Precision Frequency Reference
Most professional devices which require high accuracy and precision have an input for some sort of external frequency reference. The frequency 10 MHz is an industry standard particularly for test equipment. Most reference generators are designed for lab use and therefore are bulky and unsuitable for portable use. Abracon now offers a pocket-sized portable solution. […]

Quick look at a BPSK31 signal
PSK31 is gaining more popularity among amateur radio enthusiasts. It’s extremely small bandwidth and excellent performance in weak signal conditions make this mode perfect for low power HF stations. PSK31 is a digital transmission mode with just about 31 Hz bandwidth. The signal conveys data at a data rate of 31.25 baud and is extremely […]

Closer look at a Direct Sequence Spread Spectrum Signal
This article is going to take a closer look at the properties of a pseudo random bit sequence and a simple direct sequence spread spectrum signal both in the time- and frequency domain using the FFT capabilities of a Teledyne LeCroy WaveAce 1002. A while back, I posted an article about a Pseudorandom Number Generator […]

Pseudorandom Number Generator (PRNG)
The core of any spread spectrum (and other cryptographic) system is a pseudo random number generator (PRNG). Pseudo random numbers play a big role in the world of electronics and cryptology. The quality of a spread spectrum link and its properties strongly depend on this device. For my Direct Sequence Spread Spectrum Experiments I needed […]
