GPIB Sets the GPIB ad dress and emu la tion modes.
AD DRESS [ADDR]
Set the GPIB ad dress for the power me ter. The de fault is 13.
MODE [EMUL]
Se lects the power me ter emu la tion mode. Se lect from ML24XX
(na tive), HP 436A, HP 437B, HP 438A, or ML4803A modes.
If the em u la tion mode is changed from ML24XX (na tive) when in
CDMA mode, the sys tem will re set to stan dard read out mode.
GPIB em u la tion modes are not avail able in CDMA mode.
BUFFER [BUFF]
If BUFFER En abled is TRUE (de fault): In the ML24XX na tive
mode, 488.2 GPIB op er a tion, when a re quest for data is made the
re sponse is put in an out put buffer ready to be read by the con -
trol ler. If an other data re quest is made and the pre vi ous data has
not been read out of the out put buffer; the new data is queued af -
ter the orig i nal re quest. In this mode of op er a tion the GPIB re -
sponse buff er ing en able is TRUE, and fol low ing the 488.2
spec i fi ca tions, the re sponse should be read when ever a re quest
for data is made.
If BUFFER Enabled is FALSE: In this mode when ever a re quest
for data is made, (ex cept by se rial poll) the out put buffer is
cleared and the only data in the out put queue will be the re -
sponse to the last data re quest made. The out put buffer is cleared
once a valid GPIB data re quest com mand has been rec og nized.
