High measurement speed is essential in high-volume manufacturing of RF and

microwave components and systems. Faster testing time will improve your

productivity by enabling you to test more devices in a shorter time.

Like all the Agilent power meters, there are three types of measurement

speed settings for N1913/1914A: normal (by default), double (x2), and fast. In

normal and double modes, full sensor functionality is available. In fast mode,

averaging limits are disabled and set to 1 that allows fast measurement with

uncompromised accuracy.

When the N1913/1914A operates with the E9300 or E4410 Series power

sensors, the maximum achievable measurement speed is 400 readings/second

in fast mode. The E4418/4419B can only achieve up to 200 readings/second.

See Table 1 for specific comparisons of measurement speed.

Because of the SCPI backward compatibility, the same SCPI command for

fast measurement mode can be used between the N1913/1914A and the

E4418/4419B. Therefore, the N1913/1914A can be used directly by current

E4418/4419B users without needing software recoding. For example, using

the SCPI command of SENS1:SPE 200 sets the measurement speed on

Channel 1 to 200 readings/second. But in reality, the N1913/1914A can achieve

up to 400 readings/second in fast measurement mode while the E4418/4419B

achieves 200 readings/second only.
