MRI Analyzer Description
General
The MRI-3000 analyzer measures complex impedances of electrical components. In
particular, its design has been focused on making these measurements on the circuitry used in
MRI machines. The results of the measurements are displayed graphically, with some numeric
detail. You may choose to display the impedance from among several formats. The MRI-3000
sweeps across a range of frequencies, or operates at CW, either way the display is continuously
updated with new measurement results. This unit has many applications, including, but not
limited to:
1. Tune/align MRI coils (transmit and receive)
2. Measure Z, Phase Angle, Resistance, and/or Reactance of a load
3. Portable and economic replacement for network analyzer applications that measure S

.
4. Find resonant frequency and response curve
5. CW signal generator
6. Two plots may be simultaneously viewed on the same graph.
The MRI-3000 communicates with your PC via the MRI PC Vision
™ application software allowing the
user to remotely control the instrument or view results on the PC's much larger display, in either X-Y or
Smith Chart plot format. The impedance altering effects of coax cable can be nulled out, so that the
load at the end of the coax is displayed. The MRI-3000 operates over a wide range of characteristic
impedances, so you are not limited to measuring 50 ohm systems.
Operator conveniences include: Non volatile storage, back lit display, display brightness adjustment,
versatile output displays, and USB port communications. Internal Batteries (8 AA batteries, not
included) power the MRI-3000 in situations where wall power is not available.
