{{Catalog History}}
}}
The {{Title|General Radio 1156-A Decade Scaler}} was introduced in {{Catalog S}} and remained available through {{Catalog T}}. 

The 1156-A is a 10 to 1 divider used to pre-scale the input signal to a frequency meter or counter.  
Pairing the 1156-A to a GR counter is made easier by incorporating input and output connectors that can be relocated to the rear of the instrument.  
Included are covers for the relocated connector holes to make a clean installation.
