Step Attenuators |
 |
These Telonic step attenuators are available in nine different models with attenuation ranges from 1 to 100 dB, in steps of .1 to 10 dB. There are two basic case designs, both 1.31" diameter with lengths of 1.50" (subminature) and 2.29" (miniature). This mechanical configuration reduces panel mounting space to a minimum, and also permits incorporation of these attenuators into many existing designs.
All versions utilize Telonic solid state thick film resistive elements
for high power, precision, repeatability, and extensive service life.

Bench Type Rotary Step Attenuators |
 |
Bench type attenuators are designed as discrete instruments for use in the electronics lab, production or metrology applications such as intermediate testing or quality assurance.
The attenuators can be mounted singly or in pairs in a bench type case
as shown here.

Tandem Mounted Rotary Step Attenuators |
 |
These tandem attenuators are combinations of step units, combined in a single assembly with a single dial and dB readout. They permit instrumentation designs calling for higher dB ranges with finer step divisions.
For example, the miniature Model 8140 pictured here combines the 8121
and 8122 attenuators to provide a full range of attenuation in 1 dB steps
to 109 dB. Tandem attenuators are available in the subminiature size,
offering an attenuation range of 69 dB.

Programmable Attenuators |
 |
Telonic's line of coaxial step, digitally programmable miniature attenuators combines Telonic's thick film (distributed field) chip concept with the "edge line" conductor theory to provide relatively low-cost, highly accurate attenuator for the "OEM" automatic instrument and sytems market. The nature of the thick film chips allows higher than normal power handling capability in this size unit.
