Test Port Bias Input:

 This BNC(f) connector allows external bias to be applied at Test Port.

• Maximum voltage: ±30 VDC, typical

• Maximum current: ±1 A, (±200 mA with no degradation of RF specifications)*

Test Port Bias Fuse:

This is a bipin, non-time delay fuse rated at 1A, 125 V

Note: These connectors are NOT provided on Models E8801A, E8802A, and E8803A

*Up to 200 mA level, the instrument will meet all of its RF specifications. As the DC bias is increased, particularly at low RF frequencies (that is, typically <100 MHz, but predominantly >10 MHz), the low frequency corrected source match and directivity will degrade. Above 100 MHz RF, with up to 1 A bias, there is very little degradation in corrected source match and directivity.
