83483A Module Specifications
83483A module specifications and characteristics apply when a module is installed in the instrument mainframe. The following notes refer to the module specifications listed in this chapter.
All specifications describe warranted performance over the temperature range +10° C to + 40° C (unless otherwise noted). The specifications are applicable after the temperature is stabilized, which occurs after 1 hour of continuous operation and while module calibration is valid. Many performance parameters are enhanced through frequent, simple user calibrations.
Specifications describe warranted performance. Characteristics provide useful, nonwarranted information about the functions and performance of the instrument. Characteristics are printed in green italics.
Factory Calibration Cycle. For optimum performance, the instrument should have a complete verification of specifications once every 12 months.
Nominal Value indicates the expected, but not warranted, value of the parameter.
| Item | Description |
|---|---|
| Electrical Channel Bandwidth | 12.4 and 20 GHz |
| Transition Time (10% to 90% calculated from TR = 0.35/BW) | |
| 12.4 GHz | 28.2 ps |
| 20 GHz | 17.5 ps |
| RMS Noise | |
| Characteristic | 0.25 mV, 12.4 GHz 0.5 mV, 20 GHz |
| Maximum | 0.5 mV, 12.4 GHz 1 mV, 20 GHz |
| Scale Factor (full height is eight divisions) | |
| Minimum | 1 mV/division |
| Maximum | 100 mV/division |
| dc Accuracy (single marker) | |
| 12.4 GHz | ±0.4% of full scale ±2 mV ± 1.5% of (reading – channel offset) ±2%/°C ( Δ Tcal) (reading)–0.4%/hr ( Δ Time) (reading) |
| 20 GHz | ±0.4% of full scale ±2 mV ± 3% of (reading – channel offset) ±2%/°C ( Δ Tcal) (reading)–0.4%/hr ( Δ Time) (reading) |
| Δ Tcal represents the temperature change in Celsius from the last user module calibration. Please note that the temperature term goes to zero upon execution of a module calibration. Δ Time represents the time since the last user module calibration. The uncertainty due to time typically stabilizes after 24 hours. This term goes to zero upon execution of a module calibration. | |
| Offset Range (referenced to center of display graticule) | ±500 mV |
| Input Dynamic Range (relative to channel offset) | ±400 mV |
| Maximum Input Signal | ± 2 Vdc (+16 dBm) |
| Nominal Impedance | 50 ohm |
| Reflections (for 30 ps rise time) | 5% |
| Electrical Input | 3.5 mm |
