Front panel inputs/outputs are: RF INPUT N connector (50Ω, +20 dBm Max, 100 V DC blocking capacitor); and GEN N connector (50Ω, 0 to -48 dBm, Opt. 4 Tracking Generator generates a sweep frequency to enable the Spectrum Analyzer to make circuit response measurements, i.e. scalar network analysis).

Rear panel inputs/outputs are: J101 SMA connector (Female SMA installed for Opt. 15), J102 EXT TRIG BNC connector (10 kΩ, 50V (DC + peak AC)), J103 DB9 connector (Not RS-232 compatible. Accessory connector: Pin 1 Video Input, Pin 2 Ground, Pin 3 Video Output, Pin 6 Sweep Gate, Pin 7 Sweep Output, all others unused), J104 GPIB connector (IEEE Std 488 connector) or Opt. 08: RS-232 interface (Digital Communication Port.).
