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

ON/OFF

command

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

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

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.
