UT instrument(s) needed!!

To whom it may concern,

I need some instruments for liquid suspension ultrasound testing. Here is the list of instruments I needed and the total budget limit up to USD10,000-, but depends on the cost of them.
1. Pulser or amplifier:
a. Voltage peak to peak: >300V
b. Frequency: 1~20MHz or higher
c. Continuous wave, i.e., duty cycle=100%
d. Transducer physical properties: 2.25MHz, Impedance: 378OHM, Phase: -89.9
e. Plug-in Card preferred.

2. Ultrasound Backscattering measurement
a. Frequency: 1~20MHz or higher

3. Ultrasound nonlinearity measurement
a. Frequency: 1~20MHz or higher

If you have any question, comment, suggestion, recommend, or product information, please e-mail me before Feb. 28, 2002. Thank you for your attention.
