The HP 7000A / 70340A is a synthesized signal generator module designed for automated test equipment systems and laboratory applications requiring precision RF signal generation from 1 GHz to 20 GHz. This 4-slot MMS module delivers leveled output power greater than +8 dBm with maximum output of +13 dBm, exceptional spectral purity, and flexible modulation options including pulse, FM, and logarithmic AM. When paired with the optional HP 70341A frequency extension module, coverage extends down to 0.01 GHz, enabling broader test scenarios. The instrument provides ±0.5 dB output flatness and includes HP-IB remote control for integration into automated test systems.
