HP ESG Series Signal Generators Specifications
Phase Modulation
Input Impedance: 50Ω , nominal
Paths: FM 1 and FM 2 are summed internally for composite modulation.
Either path may be switched to any one of the modulation sources:
Int, Ext 1, Ext 2. The FM 2 path is limited to a maximum rate of
1 MHz. The FM 2 path must be set to a deviation less than FM 1.
Maximum Deviation: N x 90 radians
Resolution: 0.1% of set deviation
Deviation Accuracy (1 kHz rate): < ±(5% of deviation + 0.01 radians)
