Keysight N774-C & 8162-C Series User's Guide
Members of a growing family
The N7749C benefits from the N77-C's family-wide, common trigger
concept, and a modern, browser-accessible user interface, that makes it
convenient to configure the instrument's functionality. High-speed
measurement data acquisition, faster data interfaces, the use of
dual-ported RAM for uninterrupted simultaneous measurement and
readout, all work to minimize overhead time for repetitive measurements.
Selection Guide
•
81620C: Si detector, 450 nm to 1020 nm, low noise, best choice for 850
nm
•
81623C: Ge detector, wide 750 nm to 1800 nm range
•
81624C: InGaAs detector, highest accuracy, lowest noise
•
81626C: InGaAs detector, +26 dBm high power
•
81628C: InGaAs detector, integrating sphere, +40 dBm max, highest
accuracy at high power
Compatibility Notice
At this time, the new N7749C optical head interface supports the newly
released 81620C, 81623C, 81624C, 81626C and 81628C optical heads
and their special calibration variants. An upcoming firmware version will
add support for the previous generation optical heads 81620B, 81623B,
81624B, 81626B and 81628B.
Please note that obsolete optical heads, e.g. those of the 8152xA or
8162xA generation, are not supported by the N7749C optical head
interface and there are no plans to add support.
Likewise, 8162-C optical heads cannot be used with 81618A or 81619A
optical head interface modules or with the 8153A Lightwave Multimeter.
For further details on its application and key features, refer to the product
datasheet available on www.keysight.com.
The 8162-C family of optical power heads provide accurate power
measurements with a large area detector in a remote head for flexible
positioning. Functionality includes averaging time settings from 100 µs to
10 s, automatic power ranging, monitoring of minimum and maximum
values. Fiber adapters are available for common connector types including
MT ribbon fiber connectors and bare fiber clamps (for details, see
https://www.keysight.com/in/en/products/accessories.html).
