SPECIFICATIONS describe the instruments warranted
performance and apply &r a 30 minute warm-up. All
SPECIFICATIONS are valid over the signal generator's entire
Operatin@nvironmental
Range unless othemise noted.
SUPPLEMENTAL CHARACTERISTICS (shown in italim) are
intended to provide additional information useful in applying
the instrument by giving typical (expected), but not warranM
performance.
FREQUENCY
Range ($-digit LED display): 100 lrHz to 990 MHz.
Resolution: 10 Hz.
Switching Speed (to be within 100 Hz of carrier
frequency): <35 ms. (25ms typical at 25°C)
Accuracy and Stability: Same as timebase used.
SUPPLEMENTAL CHARACTERISTICS
Frequency Underrange: 10 kHz with uncalibmted
output.
