Modulation

Internal Digital Modulation 50% duty cycle, 200 Hz to 300 kHz

> 45% duty cycle, 300 Hz to 1 MHz

Modulation output (via Mainframe):

TTL reference signal.

External Digital Modulation > 45% duty cycle, fall time

< 300 ns, 200 Hz to 1 MHz

Modulation Input (via Mainframe):

TTL signal.

External Analog Modulation ≥ 15% modulation depth, 5 kHz to 1 MHz

Modulation input: 5 Vp-p

Coherence Control

(Agilent 81649A and 81689B)

For measurements on components with 2 m long patchcords and

connectors with 14 dB return loss, the effective linewidth results in a

typical power stability of < ± 0.025 dB over 1 minute by reducing

interference effects in the test setup.
