#About SQC

These pulse generators / sequencers allow for more versatility in experiment control by combining digital signal generation and acquisition within a single device. They are available in Eurotainer cases (series SQCT) or 19" cases (series 19SQC) with 4–24 digital output channels.

Each of the channels can be configured as a digital output or a digital input. The outputs have an internal impedance of 50 Ω, the inputs have a 50 kΩ pull-up to +5 V or can be terminated by 50 Ω. The signal levels are TTL.

Each device integrates a device-specific number of digital oscillators, digital pulse generators, counters, and logical engines:

• The digital oscillators provide a narrow pulse at their respective outputs at the end of the programmed period.
• The pulse generators are triggered by a selectable trigger input and produce a pulse with a programmable width after a programmable delay. They can be triggered periodically and can be chained to produce complex pulse sequences. Pulse generators with a burst function are available as well.
• The counters can be operated in several modes. They can count the pulses at their inputs while the counter gate is active or they may be used to precisely measure the frequency or the period of the input signal. In this case, the counter gate defines the acquisition time.
• The digital filters can be used to deglitch the input signals. The logical engines make it possible to generate complex pulse patterns by combining several signals.

The devices can also acquire digital signals. The built-in counters can detect the pulse frequency, the pulse period, or the number of pulses in a specific time interval. Besides that, each input signal can be used for triggering or enabling the oscillators or the pulse generators, it can be an input of any logical engine or it can simply be routed to any outer terminal as an output signal. Moreover, a connected computer can aquire the logical state of the signals and also issue a software trigger to start a pulse sequence.

The pulse generators / sequencers can provide TTL control signals for some of our digitally controlled devices such as switches or RF generators. They can also control other devices or receive signals from third-party devices. One sequencer can therefore control entire measurement setups or can be used e.g. as a vacuum controller or for process monitoring.
