OPERATION SYSTEM MENU

ACMod output (port 1 only) is a TTL signal synchronized to the in- ternal chopper (when used) of the signal channel. This signal can be used for synchronization with external sources or when viewing AC range (chopped) signals.

Leveling outputs - To allow the power meter to be used in a leveling loop, the sig- nal channel output is available on the rear panel. The leveling 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 SystemRear PanelBNC menu - PORT 1 for sensor A and PORT 2 for sen- sor B. Leveling 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 Pwr 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 TriggerSetupARMING is set to Blanking ON and the SensorSetupMode 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 digi- tal 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.

Configures the rear panel printer port. Select from the listed com- patible 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 ML2430A, 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.
