We are pleased to announce the release of Moku:DataLogger, our newest instrument!

Moku:DataLogger lets you log voltage data directly to an SD card for long-term measurements at rates of up to 10 kHz. The duration is limited only by the capacity of the SD card. You can also fetch previous log files from the device and upload them to Dropbox or iCloud, or send them as an email attachment.

Updates to the other instruments are detailed below.

Oscilloscope

Horizontal reference cursors: now add up to five horizontal cursors, and select one to be a reference so that all others are displayed with respect to it. Ideal for making quick time and frequency measurements.
Trigger on channels that aren't displayed: when the device is generating waveforms using the Synthesizer, you can now trigger off these signals even if they are not displayed on the screen.
Fixed a bug which would prevent pausing acquisition in roll mode.
Fixed a bug with frequency measurements in sweep and roll mode.
Fixed a bug which could cause the trigger offset to be set to zero unintentionally when using the Synthesizer drawer.

Spectrum Analyzer

Horizontal reference cursors: now add up to five horizontal cursors, and select one to be a reference so that all others are displayed with respect to it. Ideal for making quick frequency and time measurements.
Tracking generator: you can now generate sine wave outputs from within Moku:SpectrumAnalyzer. The output can be configured to sweep across the frequency range of interest. Use this feature in conjunction with max hold on the math channel to record frequency response spectra.

Phasemeter

Log frequency, phase and amplitude data directly to an SD card, as in Moku:DataLogger.
You can now generate sine wave outputs from within Moku:Phasemeter.
When connecting to a device that is running Moku:Phasemeter, the iPad will now read the instrument's settings instead of overwriting them, so you don't disrupt a measurement.

Waveform Generator

When connecting to a device that is running Moku:WaveformGenerator, the iPad will now read the instrument's settings instead of overwriting them, so you don't disrupt your experiment.

General

Now save files to Dropbox or the SD card even when your iPad is not connected to the internet.
Improvements to network reliability.
Improvements to device discovery.
Fixed a bug where instruments could become unresponsive after the connection drops out briefly.
Fixed a bug where the clock source shown in the main menu could sometimes be incorrect.
Fixed a bug which could make the app crash when two iPads connect to the same device simultaneously.
Fixed a bug which could make the words "Writing data" appear in saved screenshots in Moku:Oscilloscope and Moku:SpectrumAnalyzer.
Other minor bug fixes and improvements.
