:NCOUnts

1-15

Number of periods to
average.

:COUNt?

Reports the number of clock
counts between input pulses.

:PERiod?

Returns the period value
taking into consideration the
number of averaging counts
and system resolution. Value
is in seconds.

:ACTive?

Reports if actively counting
period. State will be zero if
not actively counting the
period.


* It should be noted that when the 9250 is in external trigger mode, it may be configured to output a single pulse,
burst of pulses, or duty cycle response of pulses upon each external input.

Notes

:PULSe[1/2/n]

Command to change the
units’ channel specific
settings.

:STATe

0/1 or OFF/ON

Enables/Disables output
pulse for selected channel.

:WIDTh

8[ns]

– 4000[s]

Sets the pulse width for the
selected channel. The
command should be sent
without units. If for example
8ns is desired the parameter
sent should be 8e-9, or the
decimal equivalent.

:DELay

+/-4000[s]

Sets the delay from the
timing reference to when the
pulse is created. The
command should be sent
without units. If for example
50ns is desired the
parameter sent should be
50e-9, or the decimal
equivalent.

:SYNC

,CHA,CHB,CHC,

CHD

Allows the user to select the
timing reference for each
channel.
*Note: Cannot set a channel
to by synced to itself

:MUX

0-15

Decimal representation of a 4
bit binary number (example:
15 = 1111)

:POLarity

NORMal /

Normal is active HIGH,
Inverted and Complement are
active LOW.

:OUTPut

Command to change the
channels’ output parameters.

:AMPLitude

3.3 - 5 [V]

Allows the user to select
adjustable TTL/CMOS output
voltages.
