1.533 Μm Frequency-Locked Laser
-
Thorlabs' LLD1530 Frequency-Locked Laser is a narrow linewidth, DFB-laser-diode-based, turnkey system with a vacuum emission wavelength of 1532.8323 nm and a high SMSR of at least 35 dB. The laser frequency is actively stabilized to a National Institute of Standards and Technology (NIST)-traceable molecular transition of acetylene and has an absolute accuracy at start-up that is better than ±25 MHz. The emission frequency immediately after start-up is then maintained with a ±25 MHz stability, providing an overall frequency accuracy of ±50 MHz. The LLD1530 is an accurate frequency reference designed to provide low-noise laser emission with excellent frequency stability, accuracy, and precision immediately at start-up. This source is ideal for use in demanding FTIR instrumentation, instrument calibration, gas sensing, and coherent telecommunications applications.

Dual Channel HV Amplifier with Phase Inverter
A400DI
-
This unit contains two independent A400 amplifiers that share common ground reference and power supply. Please see A400 page for technical details.It features also a low voltage phase inverter that inverts the signal applied to the input of channel 1. The resulting signal can then be connected to the input of channel 2 by means of a short BNC cable (supplied). As a result the two outputs operate in counter-phase. Connecting a load between the outputs effectively doubles the amplitude range. Please note that the load cannot have any connection to ground.

Quad RF Driver
-
The Quad RF Driver contains four independent RF channels, each with an RF synthesizer, variable attenuator, and 1W power amplifier. The RF signal can originate from either the internal synthesizer or an external source via SMA input. All channels have independent frequency, phase, and gain settings and can be operated in one of two modes. The “Wideband” mode operates from 35MHz to 2GHz with a 3.472KHz resolution; over this range the frequency roll-off is approximately 0.5dB/100MHz. “Int-N Phase Adjust” mode allows the user to set and maintain a fixed phase relationship between all four channels. This mode is designed to operate between 300 and 460MHz with a 2MHz resolution. Two additional inputs are provided for an external frequency reference and digital modulation.

Rotational Flow Demonstration Kit
-
The rotational flow demonstration kit detects the rotational position using the MCU’s on board data transfer controller (DTC) function, a form of state machine, while the MCU’s core is in stop-mode state. This ensures that the average power consumption is kept as low as possible, with IAV (average current) at 4.5 microampere (μA) and a 32 sample burst per second. The flow demonstration kit senses the flow direction and volumetric flow rate of water and gas, and can also detect reverse flow. The demonstration kit is applied using an active inductive method. Two coils are used to sense the rotational position of a part-metalized disk, and a third coil is used to generate a reference signal.
