Probe Tuning Devices

Morris Instruments Inc. is pleased to announce a design improvement to our line of R.F. sweeper probe tuners. We have retained all of the performance features and characteristics while reducing the overall weight by 2 lbs and the volume by 32%.

The model 405NV+, 505NV+, 610NV+, and 710NV+ RF Sweepers are used to tune probes and coils from 1.3 to 405MHz, 1.6 to 505MHz, 2.0 to 610MHz, and 2.4 to 710MHz respectively. These hand held, microprocessor controlled instruments feature; digitally synthesized RF, integral tuning bridge and detector, LCD graphic display, rechargeable battery operation, ability to operate in the fringe field of MRI magnets, and switchable one port or two port operation. All instruments now include a backlight for use in poor lighting conditions.

800 MHz to over 1 GHz Doubler Accessory

For those customers requiring the ability to tune very high frequency coils at 800 MHz and above, we have developed an external frequency doubling device which connects directly to the BNC connectors on the model 505NV+, 610NV+ or 710NV+. This device incorporates an active frequency doubler and high frequency directional coupler. With this accessory it is possible to tune the proton channel on spectrometers having a proton frequency in excess of 800 MHz. For more information about this accessory please contact Morris Instruments Inc.

ROM Version

The most recent firmware release for the NV+ models is indicated in the table below. Functionally these versions operate identically, including control of the optional backlight. Different versions are required depending on unit serial number to account for differences in internal hardware. For older units without the backlight option the current version is identical to #990601. For units with the backlight option the current version changes the method of turning the backlight on and off to make it easier to control when the room is too dark to see the screen without the backlight. Updates are available free of charge for units within the warranty period, and for a nominal charge to cover materials for out of warranty NV+ units.
