As removed from some excellent RACAL RF test equipment, all cells fully operational prior to removal (this means it works!)

Weinschel
RF Programmable Step Attenuator
Model: 5873
Design range DC to 4Ghz
0dB to 70dB in 10dB steps
Very low insertion loss
Very low IMD
SMA Female to SMA Female type Female connector at each end
In excellent condition cosmetically
NOTE: this is the original 5873, not the commonly available 5873A
Same technical specifications but different case top (removable) and labelling
It would have been nice to look inside but that top plate cover sits on top of a sealed membrane so no attempts were made to remove it.
5x side terminals - these are the control ports for the cells, each cell introduces extremely precise attenuation when activated.
Each cell is activated by a 12V DC control signal and by controlling the combination of cells activated, programmable attenuation is achieved.
Ports are 10dB, 20dB, 20dB. 20dB plus a common DC port
Complete with original mounting hardware (bolts)
COSMETIC CONDITION: Excellent
TESTING: Known to be fully operational prior to removal from the Racal test equipment (equipment obsoleted due to the main LCD display from Citizen JAPAN being badly damaged and the required replacement display is no longer available.
