5-36 PN: 10585-00001 Rev. P ML2437A/38A OM/PM
Printer [PRNSEL]
Configures the rear panel printer port. Select from the listed compatible printers which
include, but are not limited to, the following:
HP DeskJet 340
Canon BJC80
Other 300, 500, 600 Series and later HP printers are typically compatible.
For proper operation with the ML243xA, the Canon BJC80 printer must be set to the
EPSON LQ emulation mode. Refer to the printer manual for instructions on setting the
emulation mode.
Graphics
This menu presents additional graphic display controls:
CONNECT [GRCP]
This control is normally ON and causes the data between samples to be interpolated
and lines drawn between sample points. When OFF, the sample points only are
displayed as pixels.
Levelling
outputs
To allow the power meter to be used in a levelling loop, the signal
channel output is available on the rear panel. The levelling loop will
be broken every time the signal channel autoranges. To overcome
this, the outputs of ranges 1 and 2 can be made directly available on
the rear panel BNC connector. This feature is only available as a
NON DRAWN option. It can be selected from the System > Rear
Pane l >BNC menu - PORT 1 for sensor A and PORT 2 for sensor B.
Levelling A(1) selects range 1 on sensor A. If the hardware is not
available, 0 volts will be set on the appropriate output when
selected.
For signal levels below –25 dBm on a diode sensor, the leveling
outputs will not be valid as the signal channel operates in chopping
mode below this level.
TTL LEVEL
(Input port 1
only)
When in Readout or Power vs. Time operation mode, this selects the
blanking input type, HIGH active or LOW active, you are providing.
The blanking input will be used if the Trigger > Setup > ARMING is
set to Blanking ON and the Sensor > Setup > Mode is set to Custom.
When in Profile operation Mode, the blanking input is ignored.
When in Source Sweep operation Mode, if the Blanking input is set
to HIGH, the ML24xxA uses the digital input to sync to. Your
sweeper must provide a Sequential Sync output which is connected
to the digital input of the meter.
If Blanking input is set to LOW, the ML24xxA does not use the
digital input and therefore can be connected to a sweeper which does
not provide a Sequential Sync output. The ML24xxA will use the
Horizontal Ramp input only.
