Documentation

Versatile analog front-end.

Moku:Lab’s analog front-end is designed for maximum versatility. Its two 500 MSa/s inputs can be configured for AC or DC coupling, 50 Ω or 1 MΩ impedance and an input voltage range of 1 Vpp or 10 Vpp. Moku:Lab also features two 1 GSa/s outputs with 300 MHz anti-aliasing filters, allowing you to generate two high-precision waveforms while measuring on its inputs.

Precision timing

Moku:Lab features an ultra-stable internal oscillator with better than 500 ppb accuracy, as well as 10 MHz input and output references for synchronization with external timebases.

External trigger

Moku:Lab features a dedicated DC to 5 MHz external trigger input designed for TTL (1.8 to 5 Volts) voltages. Some instruments use Moku:Lab’s analog inputs as high-precision external triggers, giving you more control over your system’s trigger settings.

Freedom in the lab.

With Moku:Lab, you’re not tethered to your equipment. Control your experiment wirelessly and move freely throughout the lab with your measurements at your side.

Wi-Fi

Connect Moku:Lab to an existing WiFi network or configure it to create its own wireless network.

Ethernet

Connect to a wired network via Moku:Lab’s 100 Mbps Ethernet port. Great option in environments with WiFi congestion.

USB

It is also possible to connect to Moku:Lab via USB, allowing you to make full use of the iPad App even in WiFi restricted environments.

Moku:Lab gets better with time

Moku:Lab can receive over-the-air software updates, bringing new features to existing instruments, and giving you access to entirely new instruments. When you buy Moku:Lab, it’s just the beginning.

Noise specs

Input voltage noise

“Input voltage noise” describes the noise floor of the analog inputs and is represented as an amplitude spectral density (magnitude of input voltage noise at different frequencies normalized to a 1 Hz bandwidth). It is impossible to resolve signal features below the noise floor. Input voltage noise is a key specification for lock-in amplifiers as it can limit signal-to-noise ratio (SNR) in weak-signal applications.

ADC noise-free code resolution

Referring to the number of bits of resolution beyond which it is no longer possible to resolve individual codes, this spec is measured for 3 µs at 500 MSa/s with 50 Ω terminated inputs and calculated based on peak-to-peak ‘code noise’ at the output of the ADC with terminated inputs.

  • Units: Least Significant Bits (LSBs)
  • Noise-free code resolution = log2 (2N / [ 6.6 x σ ]) where σ is the RMS error (standard deviation) of the code noise distribution and 2N is the full range of the ADC

ADC cross-talk

Cross-talk (interference) from one ADC to the other, and is measured from 120 MHz down to 1 MHz where radio-frequency (RF) cross-talk is most severe. Cross-talk is caused by the coupling of electromagnetic radiation from one conducting element (wire) to another. The wires in electronic circuits act as antennas.
