STA-60-08-D5

Final Rev 1.4

Description:
Model STA-60-08-D5 is a direct reading,rotary vane attenuator for use in millimeterwave systems across the standard F-band
frequency range of 90 to 140 GHz. The
attenuator has a digital screen whichindicates the attenuation value directly. The
attenuator is an ideal piece of equipment inwaveguide systems where a broad direct
reading of attenuation is required. The
attenuator exhibits 2.5 dB maximum
insertion loss and up to maximum 60 dB
attenuation. The accuracy of the attenuator is 0.1 dB or 2% of the setting, whichever is larger, up to 40dB, 3% up to 50 dB, and “for reference only” above 50 dB. The attenuator is powered by a rechargeablebuilt-in battery, which can support up to 10 hours continues operation with the back light “on” and 40
hours with the back light “off”. The battery can be charged by a provided AC adapter via a standard USB
C cable or the attenuator can be operated while charging by using the AC adapter.

Note:
••
•••
•

Calibration accuracy is 0.1 dB or 2% of the setting, whichever is greater, for attenuation ranges
up to 40 dB, 3% up to 50 dB, and “for reference only” above 50 dB.
All calibration and testing are performed at +25 °C room temperature.
This product is intended to be used in a controlled lab environment. To ensure best possible
accuracy and prevent unintended behavior, please operate the unit as close to +25 °C room
temperature as possible.
The phase shift value does change while varying the attenuation.
Using AC adapter is recommended while perform the testing to avoid the sudden power loss
due to low battery power.
Eravant reserves the right to change the information presented without notice.

Caution:••Exceeding absolute maximum ratings shown will damage the device.
Any foreign objects in the waveguide will cause performance degradation and may damage thedevice.
