Keysight Technologies’ N701xA Series of single-ended active termination adapters provide extremely low noise measurement performance with a user adjustable common termination voltage (Vterm).
As signal levels of high-speed buses continue to decrease, Higher Signal-to-Noise Ratio (SNR) measurements are essential for accurate design characterization and verification.
These probes are ideal for high SNR (low noise) measurements for standards such as:
-
HDMI,
-
DisplayPort
-
MIPI M-PHY
The N701xA series includes the N7011A and N7012A adapters, both of which are similar in appearance, have the same dimensions and have a 1.85 mm (m) connector on both sides of the pod.
However, to perform connections,
-
For N7011A, use the 2.4 mm (f) to 2.92 mm (f) connector adapter (P/N: 1250-3782)
-
For N7012A: use the 1.85 mm (f) to 1.85 mm (f) connector adapter (P/N: N5520B)
Further differences in the respective specifications and characteristics are listed below.
