N8488A Power Sensor
The N8488A power sensor is calibrated to measure power levels in 10 MHz
to 67 GHz frequency range. This sensor is functional up to 70 GHz; with
typical specifications ranging from 67 GHz to 70 GHz .
The N8488A power sensor is fitted with 1.85 mm (m) connector as
standard. To convert the 1.85 mm (m) connector for calibration, an
adapter (2.4 mm (f) to Type- N (m)) is included with the power sensor.
See Figure 1- 7 .

B-models and H-models Information
The B- models (with 30 dB removable attenuator) or H- models (with 20 dB
attenuator) power sensor is a calibrated combination of an attenuator
assembly and a sensor assembly.
The attenuator and sensor assemblies are calibrated as a set and must be
used together when a specified accuracies are to be obtained. These
combination is referred to as a power sensor.
N O T E
• The 2.4 mm to Type-N adapter is intended for the use of 1 mW, 50 MHz power reference
of the power meter only. Its function as a calibration reference may be compromised if it
is used for other purpose.
• According to IEEE Standard for Precision Coaxial 1.85 mm Slash Sheet , the 1.85 mm (m)
connector is compatible with the 2.4 mm (f) connector. Hence, the adapter (2.4 mm (f) to
Type-N (m)) can be used to convert the 1.85 mm (m) connector for calibration.
