The GTX22x0 family of universal time interval counters provides all the features of stand-alone counters in PXI form factor. There are three versions of the PXI counters, GTX2210, GTX2220 and GTX2230. The GTX2210 support frequency range up to 225MHz, the GTX2220 to 1.3GHz and the GTX2230 covers frequencies up to 2GHz.
The GTX22x0 series counters have two signal input channels via BNC connectors, an external timebase, arm input, and a gate signal output. The separate input signals can be used for Arming and Gating the circuitry, and controlling the timing of the analysis (start/stop duration) for more meaningful measurements.
The GTX22x0 series counters are universal in that they provide many measurement functions of other frequency counters, including frequency, period, and time interval. The GTX22x0 series also have event counting and timing functions over a single channel, such as totalize and ratio between channels.

The Narda Broadband Field Meter NBM-550 has been designed to measure electromagnetic field strengths in the vicinity of transmitters and industrial equipment, and to evaluate and record the results in the context of human safety standards. Particular attention has been paid to ease of use. The instrument can be operated with one hand by anyone – left-handed or right-handed. The probes are isotropic, i.e. equally sensitive in all directions, so users do not need to worry about the direction the radiation is coming from.
The result data memory holds up to 5000 results along with date and time information. A GPS receiver (option) plugged into the basic unit and connected via USB gives the NBM the capability to store position data for each measurement. Instead of handwritten notes, voice comments can also be recorded. All the data can be uploaded to a PC and managed using the PC software supplied with the instrument. Measurement reports are therefore very easy to generate.
The basic unit and the probes are separately calibrated at the factory. The probe calibration data are stored in an EPROM in the probe itself. The NMB basic unit retrieves this automatically via the intelligent probe interface, and takes it into account in the results. |
