Agilent N8211A/N8212A Performance Upconverter Synthetic Instrument Module, 250 kHz to 20 / 40 GHz 307

Pulse Modulation Subsystem ([:SOURce])

:PULM:EXTernal:POLarity NORMal:INVerted

Supported Option UNU or UNW

[:SOURce]:PULM:EXTernal:POLarity NORMal|INVerted

[:SOURce]:PULM:EXTernal:POLarity?

Selects the polarity of the TTL input signal at the Pulse In front panel connector. The

N8211A/N8212A can respond to either a normal (a TTL high) or an inverted (TTL low)

signal.

Example

:PULM:EXT:POL NORM

The example selects normal (TTL high) polarity.

*RST Normal

:PULM:INTernal[1]:DELay

Supported Option UNU or UNW

[:SOURce]:PULM:INTernal[1]:DELay <num><time_suffix>|UP|DOWN

[:SOURce]:PULM:INTernal[1]:DELay?

Sets the pulse delay for the internally-generated pulse modulation using the variable

<num>[<time_suffix>]. The command, used with the UP|DOWN parameters, will change

the delay by a user-defined step value. Refer to the “:PULM:INTernal[1]:DELay:STEP" on

page 308 for setting the value associated with the UP and DOWN choices.

The optional variable <time_suffix> accepts nS (nanoseconds) to S (seconds).

The range value is dependent on the pulse period. Refer to “:PULM:INTernal[1]:PERiod" on

page 309 for pulse period settings.

Example

:PULM:INT:DEL 200E-9

The preceding example sets the internal pulse delay to 200 nS.

*RST +0.00000000E+000

Range

Internal Free Run: depends on pulse period and pulse width settings.
