Anritsu ML2430A - Manual (Page 58)

NOTE
Immediately after power-on, the “estimated operating time
remaining” displayed may not be genuine, as the battery
requires a few minutes to calculate the present rate of dis-
charge. An accurate indication will be displayed only after a
few minutes of continuous operation.
CHARGE Available only when the instrument is being powered by AC line
power or external DC power greater than 21 volts. This selection
starts the battery charging cycle. Note that the instrument will shut
down during the charging cycle, and restart automatically when the
charging is completed. A series of 10 beeps signals completion of
the charge cycle.
Rear Panel Controls for rear panel connections are located in the Rear Panel submenu.
GPIB Sets the GPIB address and emulation modes.
ADDRESS [ADDR]
Set the GPIB address for the power meter. The default is 13.
MODE [EMUL]
Selects the power meter emulation mode. Select from ML24XX (na-
tive), HP 436A, HP 437B, HP 438A, or ML4803A modes.
BUFFER [BUFF]
If BUFFER Enabled is TRUE (default): In the ML243X native mode,
488.2 GPIB operation, when a request for data is made the re-
sponse is put in an output buffer ready to be read by the controller.
If another data request is made and the previous data has not been
read out of the output buffer; the new data is queued after the origi-
nal request. In this mode of operation the GPIB response buffering
enable is TRUE, and following the 488.2 specifications, the re-
sponse should be read when ever a request for data is made.
If BUFFER Enabled is FALSE: In this mode when ever a request for
data is made, (except by serial poll) the output buffer is cleared and
the only data in the output queue will be the response to the last
data request made. The output buffer is cleared once a valid GPIB
data request command has been recognized.
RS232 Sets the serial communication parameters.
MODE [RSMODE]
Selects External Communication or Source IF. External Communi-
cation allows GPIB type commands to be sent to the power meter
over the serial interface from a local computer or a remote com-
puter via a modem.
