| Series Overview |
|
| Model | Description |
| N1810UL | Unterminated Latching:
The Keysight N1810UL is a single-pole double-throw switch available in the frequency range from DC to 26.5 GHz. In precision measurements and monitoring applications where insertion loss repeatability is crucial, these switches operate in excess of 2 million cycles with better than 0.03 dB of insertion loss repeatability at 25 °C up to 1 million cycles.
|
| N1810TL | Terminated Latching:
The Keysight N1810TL is a single-pole double-throw switch available in the frequency range from DC to 26.5 GHz. The unused port is terminated 50 Ω, making it ideal for applications where port matching is required.
|
| N1811TL | Terminated Latching:
The N1811TL is a terminated bypass switch available in the frequency range from DC to 26.5 GHz. The switch’s internal load can terminate the device under test when in the bypass mode (up to 1 watt). Because of its compact design, it is ideal for drop-in, dropout applications.
|
| N1812UL | Unterminated Latching:
The N1812UL is a versatile, unterminated 5-port switch available in the frequency range from DC to 26.5 GHz. In transfer switch applications, the fifth port can be terminated externally with a high-power termination. It can also be utilized for signal path reversal or as a calibration port.
