Spectrum Analyzer overview

Moku:Lab’s Spectrum Analyzer allows you to observe input signals in the frequency domain between DC and 250 MHz. View two channels of data simultaneously with a resolution bandwidth as low as 1 Hz over a minimum span of 100 Hz. The Spectrum Analyzer also features two integrated waveform generators capable of producing sine waves at up to 250 MHz.

Features

Display and record power spectra or power spectral densities in the frequency domain from DC to 250 MHz
Quickly measure key metrics by dragging measurement cursors onto features of interest using the iPad’s multi-touch interface
Additional display settings: Video bandwidth filtering, Averaging, Persistence
Generate two sine waves up to 250 MHz using Moku:Lab’s built-in analog outputs

Specifications

Frequency Range: DC to 250 MHz
Frequency Span: 1 kHz to 250 MHz
Resolution Bandwidth (RBW) modes: Auto, Manual, or Min
Minimum RBW: 1 Hz
RBW Windows: Blackman-Harris, Flat top, Hanning, None
Dual channel sine-wave generator frequency range: 1 mHz to 250 MHz

Measurements, and more

The multitouch user interface really shines with Moku:SpectrumAnalyzer. No need to wrestle with frequency range settings and start/ stop/ span inconsistencies. The Spectrum Analyzer features a frequency range of 200 MHz (extended to 250 MHz in software) and resolution bandwidths down to 1 Hz, all with super fast update rates thanks to the DSP power of Moku:Lab’s FPGA.

Moku:SpectrumAnalyzer inherits the best features from Moku:Oscilloscope: tracking cursors, averaging, persistence and, of course, simple sharing of data via DropBox, iCloud and email. A math channel in Moku:SpectrumAnalyzer includes options to display Max Hold or Min Hold data of a channel. You can display your data with a log or linear power spectrum or power spectral density or even visualize the evolution of spectra with 3D waterfall plots.

F.A.Q.

How do I track a peak?

Simply drag out a new marker from the marker button. Track multiple peaks on a single channel by dragging markers directly to the peaks you want. The Measurements Panel is also marker aware. Make measurements based on a marker’s characteristics such as amplitude, frequency, 3 dB width and SNR, or even the difference between markers. Swipe up from the measurement area to reveal the measurement history, a powerful enhancement to conventional zero-span measurements.

How do I generate waveforms on Moku:Lab’s analog outputs while running the Spectrum Analyzer?

Moku:SpectrumAnalyzer can be configured to generate two independent sine waves up to 250 MHz each on Moku:Lab’s analog outputs. In the Moku:Lab App, open the instrument Configuration Panel by tapping on the settings icon (located on the top-right corner of the screen). Select the Output tab, then configure and turn on the desired channel(s).
