Specificaties
| Multiple Operating Modes | The CNG-EbNo provides five operating modes: carrier-to-noise (C/N), carrier-to-noise density (C/N₀ ), bit energy-to-noise density (Eb/N₀ ), carrier-to-interferer (C/I), and power meter. The instrument can also be used as a precision noise generator. |
| Custom Configurations | The CNG-EbNo is available in a variety of configurations to meet your specific testing needs. Applications include: military communications WCDMA SATCOM NASA TDRSS CableTV HDTV IS-95 CDMA TSMA UMTS GPRS L-band modems Milstar Inmarsat Intelsat General Purpose. |
| Direct Display of Eb/No, C/N, C/I, or C/No | The 6.25” color TFT touch screen provides simultaneous readout of all significant input and output signal levels relating to the chosen operating mode, including carrier-to-noise ratios. |
| Accuracy of 0.2 dB RSS | A special, large-dynamic-range power meter measures both the signal and the noise, which allows the CNG-EbNo to set the desired ration to within ±0.2 dB. Special configurations can provide improved accuracy. |
| Bit Rate Entry of 1 bps to 999 Mbps and above | In bit energy-to-noise density testing (Eb/No ), the instrument automatically calculates noise density based on the user specified bit rate. |
| Variable Output Power | Output power is user-specified and can be set within the range of -55 dBm to +5 dBm. |
| True RMS Power Meter | The digital power meter is custom designed to cover the frequency range of the particular instrument. It can measure signals and noise accurately with Gaussian Noise crest factors up to 18 db. |
| Direct Testing at both RF and Microwave Frequencies | In configurations that cover two separate frequency ranges, measurements can be made directly without the need for special conversion circuitry. |
| Feature | Parameter |
| Carrier Path | Input Power Range: -55 dBm to +5 dBm Maximum Input Power: +21 dBm (with no damage) Output Power Range: -55 dBm to +5 dBm |
| Noise Path | Output Power Range: -55 dBm to +5 dBm Ratio Accuracy: ±0.2 dB RSS, ±0.3 dB WCU Power Meter Range: -55 dBm to +5 dBm Power Meter Accuracy: ±0.5 dB |
| Primary Power | Operating Temperature: 0° to 50° C Dimensions: 17” W x 5.25” H x 17.5” D |
