Supplementary Performance Characteristics
Characteristics
Output isolation (typ): 50dB
Return loss (typ): 60dB (except option 021).
Operating Modes
Internal Modulation
Modulation frequency: 250Hz to 300kHz (squarewave)
Duty cycle: 50% xed
Modulation depth: 100% (on/o)
Modulation output: TTL reference signal. Max power reduced by 1dB.
External modulation
Modulation frequency: 200kHz to 20MHz (at 3dB optical bandwidth, typ)
Modulation depth (max, typ):
6
15%
Coherence Control
Eective linewidth of 50 to 500Mhz typ (30-500MHz typ for HP 8168D).
For measurements on components with 2m long patchcords and connectors with
14dB return loss, the eective linewidth results in a typical power stability
of
<
6
0.025dB (
<

0.1dB for HP8168D) over 1 minute by drastically reducing
interference eects in the test setup.
