TCXO -
Epson Toyocom
A TCXO (Temperature compensated crystal oscillator) is a crystal oscillator with a temperature-sensitive reactance circuit in its oscillation loop to compensate the frequency-temperature characteristics inherent to the crystal unit. Epson's are classified into two types. One is a Direct-Type TCXOwith a temperature compensation circuit built into the oscillation loop. The other is an Indirect-Type TCXO with a temperature compensation circuit outside the oscillation loop, in which the oscillation frequency is therefore indirectly controlled.

TCXOS & VCTCXOS -
IQD Frequency Products Ltd
Temperature Compensated Crystal Oscillators (TCXO) deliver excellent temperature characteristics combined with low power consumption and fast warmup. Voltage Controlled Temperature Compensated Crystal Oscillators (VCTCXO) combine the same excellent temperature characteristics, low power consumption and fast warmup with a voltage control function to allow precise tuning of the output frequency after PCB assembly and later, to compensate for any effects of aging as well as offering the ability to pull back to nominal frequency where there is a change of circuit conditions

OCXOS -
IQD Frequency Products Ltd
Oven Controlled Crystal Oscillators (OCXOs) deliver the ultimate piezo electric performance with stabilities down to less than ±1ppb. An OCXO offers frequency stabilities even tighter than those offered by a TCXO.

BioAge s.r.l.
During an experiment to detect an affinity reaction on biological material, a molecule of interest is attached to the quartz crystal of the measurement channel, this deposition can be achieved by direct binding or by capture through another protein, the result of this process is to make the quartz sensitive to the molecule to be detected.

VCXO -
Epson Toyocom
A VCXO (Voltage Controlled Crystal Oscillator) is a crystal oscillator the output frequency of which is controlled by adding an external control voltage via a frequency control input on a variable capacitance component such as a varactor diode connected in parallel to a load capacitance (CL). Epson VCXOs are divided into two types according to Voltage-Frequency (V-F) characteristic slopes depending on the AFC (Automatic Frequency Control) input configuration of the VCXO. One is a VCXO with a positive V-F slope and the other is a VCXO with a negative V-F slope. Please note that the input voltage of a control circuit will vary according to the individual type, as shown in Figs. 3 and 4. Epson's VCXOs are capable of either, depending on the customer's preference. Epson's VCXOs have been increasingly used for broader applications such as slave oscillators in phased-lock loops, or frequency modulators. Among the above types, a VCXO combined with a TCXO is called a VC-TCXO , respectively. These components have the merit of delicately controlling their output frequency electrically.

400C Series -
CH Instruments, Inc.
The quartz crystal microbalance (QCM) is a variant of acoustic wave microsensors that are capable of ultrasensitive mass measurements. Under favorable conditions, a typical QCM can measure a mass change of 0.1-1 ng/cm2. QCM oscillates in a mechanically resonant shear mode under the influence of a high frequency AC electric field which is applied across the thickness of the crystal. Figure 1b below shows an edge view of a QCM crystal undergoing oscillatory shear distortion. The central portions of the top and bottom of the crystal are coated with a typically disk-shaped thin metal film (e.g., gold).

BioAge s.r.l.
Elettra has been designed to operate on its own, but it is also possible to connect it to a PC to control it and acquire, view and save data thanks to its extremely easy to use software that runs under MS-Windows™. The data acquisition process can be controlled extremely quickly thanks to the PLAY, PAUSE and STOP keys. Captured data can be saved in an Excel compatible format and graphs saved as bitmap images. By clicking on a button, the software is able to open the Excel program installed on the PC, enter all the data and create countless graphs, ready to be inserted in your documents and publications. At any moment it is possible to take a picture of the graph showing the frequency variation and save it as a bitmap image, to be able to insert it in documents and publications. The same keys that are present on the instrument are found on the software, these allow you to control the instrument remotely. On the frequency variation graph it is possible to zoom in on the regions of interest, it is also possible to display two cursors on the graph, thanks to these cursors it is possible to easily and immediately calculate the value of the frequency variation between any two points on the graph. The software is extremely easy to use and performs many other useful functions, such as automatic recognition of the computer port to which the instrument is connected. BioAge builds tools and writes software only after having carefully listened to the needs and requirements of the users of the final products, this process has the purpose of creating products that are easily usable and that have all the characteristics and functions that the user expects to have.
