The Wavetek 2001 is a versatile sweep/signal generator spanning 1 to 1400 MHz across three overlapping bands. It delivers continuous-wave, swept, and delta-frequency operation across laboratory, service, and production environments. The instrument combines broad frequency coverage with flexible modulation, remote control capability, and modular marker provisions—all within a compact 50 Ω output stage designed for reliable, repeatable measurements.
