RITEC introduces the highest power toneburst pulser on the market.

Warwick RI, USA, June 1, 2003- RITEC proudly introduces the new compact RPR-4000 pulser/receiver. Ideal for low sensitivity applications such as those using EMATs, and air-coupled piezoelectric transducers, the RPR-4000 provides the most powerful tone burst available (up to 8 kW). Designed to withstand severe environmental pollution and high temperatures, the RPR-4000 includes a digital synthesizer, a high duty cycle RF amplifier, a low noise broadband receiver, and a diplexer for single transducer operation. The high power makes the RPR-4000 ideal for driving low efficiency transducers such as electromagnetic acoustic transducers (EMATs) or air-coupled transducers.

RITEC introduces a new standalone broadband receiver, the BR-640A

Warwick RI, USA, June 1, 2003- RITEC introduces a new broadband receiver, the BR-640A. Replacing the BR-640 receiver, the new BR-640A offers identical performance in a new cabinet. Further information may be found by downloading the specifications at http://www.ritecinc.com/br-640a.pdf.

 

New SP-801A expands the frequency range as it replaces the SP-801 square wave pulser

Warwick RI, USA, June 1, 2003- RITEC introduces an improved square wave pulser to replace the older SP-801 square wave pulser. The new SP-801A square wave pulser has an expanded frequency range covering between 50 kHz to 10 MHz, in 4 adjustable frequency ranges, along with four fixed frequency ranges. The SP-801A also has an higher duty cycle. The specifications may be found at http://www.ritecinc.com/sp801a.pdf.

New RM-136 modulator for the SNAP system

Warwick RI, USA, March 1, 2002- RITEC releases a new modulation module for the RITEC SNAP Ultrasonic Measurement System. The RM-136 module provides many improvements in performance over the older RM-75 modulation module. Utilized in many nonlinear measurements, the modulation module allows the outputs of two RF sources to be combined in various combinations such as Hanning, or as a linear sum. Unlike the older RM-75 module, the RM-136 module allows the amplitudes of each of the RF signals to be controlled independently when combined as a linear sum. The maximum frequency for the modulation module is approximately 100 MHz.

GA-5000 standalone gated amplifier replaces GA-10000 gated amplifier

Warwick RI, USA, January 17, 2001- RITEC announces the release of the RITEC GA-5000 high power gated amplifier. The new amplifier, which replaces the GA-10000 amplifier in the RITEC product lineup, offers similar performance as the GA-10000 in the more modern PF-5000 power frame. The GA-5000 has front panel controls over the repetition rate, burst with , high power pulse amplitude. Unlike the GA-10000, it contains a high efficiency, power factor corrected power supply which accepts 50-60 Hz, 80-240VAC power with out requiring adjustments. The GA-5000 also uses the RITEC RM-79 gated amplifier which is used in the flagship SNAP system and offers a low distortion high power RF toneburst of up to of 80 MHz.

New High Frequency Triple Direct-digital-synthesizer module for SNAP systems

Warwick RI, USA, July 1, 2002- RITEC releases a combined synthesizer and timing module for the RITEC SNAP Ultrasonic Measurement System. The RM-116 module provides many improvements in performance over the older combination of the RM-63 timing module,the RM-64 synthesizer module and the RM-75 dual delay timing module. In addition to combining the functions of three modules into a single module, the RM-116 module can also operate at increased frequencies, can accept different clock frequencies and provides increased control over the delay and width of the high power outputs of the high power tonebursts from the SNAP system. The maximum frequency for the output from each of the new synthesizers is approximately 125 MHz, operating with a clock of 20 MHz and a multiplier of 20, whereas the older synthesizer module had a maximum frequency of 33 MHz, operating with a clock of 80 MHz.

Direct-digital-synthesizer module for RAM-10000 and RAM-5000 systems

Warwick RI, USA, January 17, 2001- RITEC announces the release of a new synthesizer module for the RITEC RAM-10000 and RAM-5000 Advanced Ultrasonic Measurement Systems. The new module, model RM-113, offers several improvements over the older RITEC synthesizer module, RM-46. It can accept clock inputs over a wider frequency range up to 300 MHz, with an internal clock multiplier function, which allows the continuous wave (CW) output to cover a larger range of frequencies. The maximum frequency for the output from this new synthesizer is approximately 50 MHz, operating with a clock of 25 MHz and a multiplier of 6x, whereas the older synthesizer module had a maximum frequency of 23 MHz, operating with a clock of 80 MHz.

The amplitude of the output from RM-113 is much less frequency dependent than the output from the older RM-46 synthesizer module; the decrease in the amplitude at 40 MHz is approximately 1 dB, as contrasted with over 14 dB in the older RM-46 synthesizer module. Further, the spectral quality of the output from the new RM-113 is greatly improved.

The RM-113 will allow both RAM-10000 and RAM-5000 systems to operate to 40 MHz in the Mark IV (pulser/receiver) configuration, and to approximately 25 MHz in the Mark VI configuration (complete measurement system).

Further information on the RM-113 will be available in the PRODUCTS link of the www.RitecInc.com website.

Gated integrator module for RAM-10000, RAM-5000
and SNAP systems

Warwick RI, USA, December 1, 2000- RITEC releases a new gated integrator module for the RITEC RAM-10000 and RAM-5000 Advanced Ultrasonic Measurement Systems. The RM-106A contains a pair of matched integrators, integrating each of the dual outputs from the phase detector module over a specified time interval at a designated rate of integration. The older integrator module, RM-24A, allowed the integration rate to be set to one of eight (8) settings over the range of 2.7 kHz to 1.6 MHz. The new RM-106A allows the integration rate to be set to one of sixteen (16) settings over the frequency range of 454 Hz to 2 MHz. This permits the RM-106A integrator module to be used in nuclear quadrapole resonance systems without modification. It also permits finer control of the integration rate during measurements of the amplitude and frequency of acoustic resonances in a variety of samples.
