1. INTRODUCTION
1.1. FUNCTIONAL DESCRIPTION
The Model 9340 is a Family of Precision Decade Resistance Boxes. It combines
techniques established at Guildline in the construction and stabilizing of resistors, and
low uncertainty switching techniques used in many of our instruments. The Model 9340
Series is available in decade range of from 3 to 7 decades. Each range is available in the
full resistance range of from 0.01 steps to 1 Tsteps.

1.2. FEATURES
The main features of the Model 9340 series are:
•Resistance range from .01 to 11 T
•Accuracy better than 0.01%
•Temperature coefficient less than 5 ppm/oC
•Zero resistance less than 1 m/decade
•High reliability switches noted for 1,000,000 cycles
1.3. GENERAL THEORY
The 9340 series of decade boxes consist of 3, 4, 5, 6 or 7 decades of resistors switched in
a series circuit. Figure 1-1 illustrates schematically the circuit of the Model 9347. The
Models 9343, 9344, 9345, 9346 and 9347 are identical except for the number of decades.
The value of the resistances are related to the total resistance of the unit. These values
are listed in Table 2-2.
