[:SOURce]:PM[1|2]

Syntax

[:SOUR]:PM[1|2][?]

Form Set & Query

Description Enables the jitter modulation.

Parameter OFF|ON

*RST value OFF

Example Enable the jitter modulation on channel 1.

PM1 ON

[:SOURce]:PM[1|2]:SENSitivity

Syntax

[:SOUR]:PM[1|2]:SENS

Form Set

Description Sets jitter modulation sensitivity.

You now have to apply an external source (–0.5 V … 0.5 V max)

for jitter modulation to the Delay Control Input at the instrument’s

front panel:

• If you apply a source of 500 mV, the signal delay will be

increased by 250 ps/25 ps.

• If you apply a source of –500 mV, the signal delay will be

decreased by 250 ps/25 ps.

Between –500 mV and +500 mV, the signal delay

increases/decreases lineally to the Delay Control Input, for

example, a source of +200 mV results in a delay of 250 ps/V * 200

mV = 50 ps.

Parameter 25ps|250ps

Jitter modulation is turned on with fixed sensitivity of 50 ps/V or

500

ps/V.

*RST value 25 ps

Example Set the delay control input to 25 ps.

[:SOUR]:PM[1|2]:SENS 25ps
