4530 Series RF Power Meter

Remote Operation

TKMK2

Description:

Sets the talkmode to return the reading at marker 2 for the active channel each time the 4530
is addressed to talk. This is a “permanent” talkmode, and will remain in effect until a new
talkmode is set. Power is returned in current units.

Syntax:

TKMK2

Returns:

Pwr@Marker2

Valid Modes:

Pulse and Statistical modes

Restrictions:

MARKer:MODe

must be set to VERT.

SYSTem:LANGuage

must be set to BOON to use

native mode instructions.

TKPLSTIM

Description:

Sets the talkmode to return an array of automatic timing measurements performed on a
periodic pulse waveform each time the 4530 is addressed to talk. Measurements performed
are: the frequency, period, width, offtime and duty cycle of the pulse waveform, and the
risetime and falltime of the edge transitions. For each of the measurements to be performed,
the appropriate items to be measured must be visible on the screen if the power meter is
place in GRAPH mode. Pulse frequency, period, offtime and duty cycle measurements
require that an entire cycle of the pulse waveform (minimum of three edge transitions) be
present. Pulse width measurements require that at least one full pulse is visible, and are
most accurate if the pulse width is at least 15% of the screen width (timespan). Risetime and
falltime require that the edge being measured is visible, and will be most accurate if the
transition takes at least 5% of the screen width. It is always best to have the power meter set
on the fastest timespan possible that meets the edge visibility restrictions. Set the trace
averaging as high as practical to reduce fluctuations and noise in the pulse timing measure-
ments. Note that the timing of the edge transitions is defined by the settings of the

and

settings; see the descriptions for those

commands. This is a “permanent” talkmode, and will remain in effect until a new talkmode
is set. Power is returned in current units.

Syntax:

TKPLSTIM

Returns:

PulseFreq, PulsePeriod, PulseWidth, Offtime, DutyCycle, Risetime, Falltime in fundamental
units

Valid Modes:

Pulse mode only

Restrictions:

Timespan must be set appropriately to allow measurements (see above).

SYSTem:LANGuage

must be set to BOON to use native mode instructions.
