STG-10-S2

W-Band Noise Figure and Gain Test Extenders, Low
Noise Figure
STG-10-S2 is a full W-Band noise figure and gain test extender that
extends the noise and gain measurement capabilities of common andlow frequency signal synthesizers and noise figure meters to thefrequency range of 75 to 110 GHz. This extender offer low noise figure
and is designed to interface with industry standard noise and gain testsystems, such as Keysight 8970A/B and Y Factor with a spectrum
analyzer. It can also interface with most noise and gain analyzers in the10.0 MHz to 26.5 GHz frequency range.

NOTE:
•••

•

All data presented is collected from a sample lot. Actual data may vary unit to unit, slightly.
All testing was performed under +25˚C case temperature.
The Triggering Port (female SMA connector) of the noise source is provided to turn the noise source on and off via a TTL
control signal any time the Bias is applied. The switching frequency is limited to 1 KHz.
The Power/Triggering Inversion Switch of the noise source is provided to manually turn the noise source on and off anytime the Bias is applied. When the switch is in the “ON” position, the LED light will be illuminated.
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 possible device damage.
