excellent technical specifications have been a distinguishing mark of rohde & schwarz emi test receivers right from the beginning. each r&s®esib model continues this tradition with the following characteristics:
| frequency range | |
| input 1 | 20 hz to 7 ghz / 26.5 ghz / 40 ghz depending on model |
| input 2 | 20 hz to 1 ghz |
| preselection | 9 or 10 preselection filters depending on model can be switched off in analyzer mode |
| resolution bandwidths (receiver and analyzer mode) | |
| 6 db bandwidths emi bandwidths |
10 hz to 10 mhz, in decimal steps 200 hz, 9 khz, 120 khz, 1 mhz acc. to cispr 16 tolerance |
| resolution bandwidths (analyzer mode) | |
| 3 db bandwidths | 1 hz to 10 mhz, in steps 1/2/3/5 |
| displayed average noise level | ||
| receiver mode; 0 db rf attn.; preamp. 20 db |
