9214+ Quantum Composers Pulse Generator

The 9214+ is a pulse generator from Quantum Composers. A pulse generator is a piece of electronic test equipment that engineers use to generate rectangular pulses. An electromagnetic pulse generator is best for digital, not analog, circuits. Engineers can inject pulses into a piece of equipment under test as a stimulus as they test the device, using pulses to confirm the equipment’s proper operation.

The Quantum Composers 9214+ Sapphire Plus is an upgrade to the standard Sapphire, with this upgraded version you will have better performance but still retain great value. This unit is perfect for those on a budget but looking for better resolution and jitter.

The Sapphire Plus, with 2 or 4 independent outputs, gives you features and spec’s not found on our standard 9200. The resolution and accuracy of the width, delays, and period counters improves to 5ns. This allows for finer adjustments (5ns) on the widths, delays and period. Also new are the virtual channels which effectively double the number of channel timers the unit may utilize, the 2 channel model adds 2 “virtual” channels and the 4 channel model adds 4 “virtual” channels. A “Period Counter” has been added which measures the time between incoming external trigger pulses.

The Sapphire Plus also has an optional 1ppm crystal oscillator for improved performance. With intuitive, streamlined GUI control of timing parameters and quick recall of up to 6 system configurations, the instrument is instantly ready for use. Complete control of the Sapphire is provided through the standard USB interface and optional Bluetooth connectivity.

Bluetooth Wireless Connectivity

The Bluetooth wireless capabilities are truly unique with the sapphire series. With the Bluetooth option, you can control the instrument wirelessly using the included software application, Comm Terminal or other terminal program. This unique feature allows you to communicate with Bluetooth equipped devices, such as laptops and some tablets or smartphones.

Graphical User Interface

The Sapphire uses an included software application as the primary means of communication. The software allows simple and easy control of the unit via USB or optional Bluetooth wireless, enabling the user to create complex pulse trains and save them for future recall. The software also allows users to manually input SCPI (Standard Commands for Programmable Instruments) based commands via the Command Terminal Section.
