[:STATe]?
OUTP[:STAT]?
queries the
HP
E1440A
to discover whether an
output is meant to be available at the front panel connector.
:AMPLify
High Voltage Option 001
The :OUTP:AMPL[:STAT] command takes a boolean argument and
switches the Option 001 high-voltage amplifier into the output signal
path. This amplifier has a fixed amplification factor of 4.

Comments

The high-voltage amplifier is specified for a load of 500
a,
the
normal output impedance is 50
0.
Name
ONlOFFlllO
rn
The HP E1440A treats the high-voltage amplifier as an external
accessory. This means that the programmed output voltage is not
changed when the high-voltage amplifier is switched ON or OFF,
but the output level will increase or decrease by a factor of four.
When queried, the HP
E1440A responds with the true output
voltage, provided the impedance of the connected device matches
that of the module.
Type
boolean
rn
The high-voltage amplifier is an installable option, if it is not
installed, an error is generated. See *OPT? in
Common Commands
section later in this chapter.
Values
ONlOFFlllO
rn
The high-voltage amplifier has a maximum frequency of 1MHz. It
cannot be switched on if
:FREQ
>
1MHz. Whilst it is ON,
:FREQ
is limited to SlMHz.
