■NMR POWER AMPLIFIER(BIAS-GATE PULSE AMPLIFIER)
This device is designed to act as a high performance power amplifier for Nuclear Magnetic Resonance (NMR). It is an all solid-state high-speed pulse amplifier.
For acquiring NMR data, noise from the transmitter to the receiver must be minimized. A conventional method is a series of cross diodes to suppress the noise.
However, the amplifier does not require a conventionnal noise suppressor, eliminating power loss due to cross diodes.
The product has a digital display that shows the power level of the FWD and REV power for pulses as short as 1.5μSec.

■PRE-AMPLIFIER
This product is a low-noise amplifier with the features of large-signal gain as well as 30dB, low noise level and a very short dead time.
The PRE-AMPLIFIER is a device that amplifies faint FID signals in the initial reception stage of NMR measurements.

■HETERODYNE RECEIVER
This is a double heterodyne receiver with low noise and large-signal gain designed for NMR measurement.
It is possible to use it through wideband without adjusting.

■UNIT TYPE RECEIVER
This receiver is divided into units of ①1'st Amp, ②2'nd Amp, ③PSD, ④DC-Amp, and ⑤REF-phase shifter. The frequency range of each unit can be extended if necessary.
It is very easy to use, and the price is low.

■NMR PULSE GENERATOR
Pulse settings can be changed with Windows 7/XP software, and the bus is not an issue as the device is connected to the PC by USB.
Because our AD board (AD12H25AT/U) can be built into same BOX, automatic measurement can be enabled.

■HIGH-SPEED A/D BOARD
This device converts the input analogue signal into a digital signal, allowing extremely high-speed quantity surveying and estimation.
It is possible to use it built-in with our N210-1026E pulse generator.

■DUPLEXER
It is possible to use as a transmit-receive switch when doing NMR scanning.
Because the leakage of the amplifier power to the receiver side can be reduced when transmitting, the effect on the receiver can be reduced.

■LOW TEMP. PRE-AMPLIFIER
This device was developed to decrease noise from having a large effect when minute signals are measured.
Because use at low temperatures is possible, the thermal noise in the pre-amp input component can be decreased compared with use at normal temperatures.
S/N of the NMR signal improves, and measurement time can be shortened.
