R&S®ESIB EMI Test Receivers
Standard-compliant EMI measurements up to 40 GHz
Characteristics
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 |
