Anritsu ML2430A Optimizing Readings, Send fast mode on Send0, 13, Fast ON, 7L, NLend

OPTIMIZING READINGS PROCEDURES

Send(0, 13, “O 1”, 3L, NLend);

Receive(0, 13, buffer[i], 20, STOPend);

}
Settling (%)	Power Level (dBm)	Readings/Second
0.1	0	160
0.1	–30	160
10.0	–30	160

The 0.1% settling on –30 dBm power level results were not improved because of the amount of time needed to settle to 0.1% on –30 dBm.

FAST Using the FAST command (page 6-37)limits the types of measurements that can

ON/OFF be taken. As some processes are turned off, higher measurement speeds can be

command achieved. FAST will not operate when sent via RS232. When THE FAST ON command is selected, the readout display is also turned OFF.

NOTE

Using FAST mode only increases speed when asking for one measurement at a time, using the ‘Receive’ command.

C code example:

/* send fast mode ON*/

Send(0, 13, “FAST ON”, 7L, NLend);

/* Setup the power meter into talk addressed. In this mode */ /* we can read from power meter without readdressing each */

/* time.			*/
Receivesetup(0,13);
/* Now read 10 readings */
for (loop = 0; loop < 10; loop++)
{
RcvRespMsg(0,buffer,STOPend);
}
	Settling (%)	Power Level (dBm)		Readings/Second
0.1		0		150
0.1		–30		150
10.0		0		610
10.0		–30		250

The 0.1% settling on –30 dBm power level results were not improved because of the time needed to settle to 0.1% at –30 dBm.
