R&S®ESCI EMI Test Receiver
For compliance tests meeting all civil standards from 9 kHz to 3 GHz
Characteristics
The R&S ESCI is backed by decades of experience gained by Rohde & Schwarz in the development of test receivers and spectrum analyzers. The test receiver's advanced design concept offers the following characteristics:
| Frequency range | 9 kHz to 3 GHz | |
| Preselection | 11 preselection filters can be switched off in analyzer mode | |
| Resolution bandwidths (receiver and analyzer mode) | ||
| 3 dB bandwidths | 10 Hz to 3 MHz, in steps of 1/3/10 | |
| 6 dB bandwidths | 200 Hz, 9 kHz, 120 kHz acc. to CISPR 16 tolerance | |
| Pulse bandwidth | 1 MHz | |
| FFT filters | 1 Hz to 30 kHz, in steps of 1/3/10 | |
| Channel/RRC | 44 filters between 100 Hz and 5 MHz | |
| Displayed average noise level (DANL) | ||
| Receiver mode; 0 dB RF attn.; preamp. 20 dB | ||
| 9 kHz to 150 kHz (RBW 200 Hz) | –15 to –20 dBμV | |
| 0.15 MHz to 30 MHz (RBW 9 kHz) | –4 to –14 dBμV | |
| 30 MHz to 1000 MHz (RBW 120 kHz) | <–4 dBμV | |
| 1 GHz to 3 GHz (RBW 1 MHz) | <6 dBμV | |
| Intermodulation | ||
| 1 dB compression point of input mixer f > 200 MHz; 0 dB RF attn.; preamp. + presel. off |
5 dBm nominal | |
| Total level uncertainty | ||
| without preselection/preamplifier | ≤0.5 dB | |
| with preselection/preamplifier | ≤1.0 dB | |
| Measurement speed | ||
| Sweep (analyzer mode) | 1 µs to 16.000 s (zero span); resolution 125 ns 2.5 ms to 16.000 s (span ≥ 10 Hz) | |
| Scan (receiver mode) | 100 μs to 100 s (selectable) | |
| Max. input level | ||
| RF attn. ≥ 10 dB; CW RF power | 30 dBm | |
| Max. pulse voltage (10 μs) | ||
| RF attn. ≥ 10 dB | 150 V | |
