HP ESG Series - Φ M Start Rate

5-102
Hardkey and Softkey Reference
Phase Modulation
ΦM Start Rate
Use this softkey to change the starting internal modulation frequency for
swept-sine phase modulation. To change the value, press the softkey once. The
current value for the
ΦM start rate is displayed in the active entry area. To enter a
new value, rotate the front panel knob until the desired value is displayed, use the
up and down arrow keys, or enter the value using the numeric keypad and press
the
Hz or kHz terminator softkey. The range of values allowed is 0.1 Hz to 50 kHz.
The minimum increment allowed is 0.1 Hz.
This softkey is coupled to the
ΦMRate softkey in the initial ΦM Menu and the
ΦMTone1Rate softkey in the ΦM Dual-Sine Menu. Any value set for
ΦMStartRate is reflected in the ΦMRate and ΦMTone1Rate softkeys.
Conversely, if you change the value for either the
ΦM Rate softkey or the
ΦMTone1Rate softkey, the value for ΦMStartRate is changed to match.
Softkey Location: Press
FM/ΦM hardkey, toggle FM/ΦM softkey to ΦM, press
