Overview

NOTE

Solenoid (K4) and associated circuitry are not available in models 8495G and 8495H.

Figure 1 Typical Four Section Attenuator Schematic Diagram

Table 1 and Table 2 on page 3 and Table 3 on page 4 show the typical switching arrangement to increase the amount of attenuation in an 8494G/H, 8495G/H, or 8496G/H in a linear manner. To ensure specified performance, it is recommended that the attenuator sections that are shown in the following tables be used. With the attenuator programmed for 0 dB attenuation, the resultant attenuation is the insertion loss (residual attenuation). The 8494G/H has a minimum selectable step of 1 dB, while the 8495G/H and 8496G/H have a minimum selectable step of 10 dB. The accuracy of the attenuators is within the limits given in Specifications, page 6.

•The 8494G/H are four-section attenuators with a maximum attenuation of 11 dB.

•The 8495G/H are three-section attenuators with a maximum attenuation of 70 dB.

•The 8496G/H are four-section attenuators with a maximum attenuation of 110 dB.
