STG-12-S1

E-Band Noise Figure and Gain Test Extenders
STG-12-S1 is an E-Band noise figure and gain test set that extends thenoise and gain measurement capabilities of common and low frequency
signal synthesizers and noise figure meters to the frequency range of 60
to 90 GHz. This extender is designed to interface with industry standard
noise and gain test systems, such as the Keysight 8970A/B and Y Factor
measurements with a spectrum analyzer. It can also interface with mostnoise and gain analyzers in the 10.0 MHz to 1.6 GHz frequency range.

All data presented is collected from a sample lot. Actual data may vary unit to unit.
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 any
time 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.
