The person above average of economy signal generator
HP8647A and stability of function of signal generator of 8648A/B/C/D series synthesis, reliable, price is low. These a few kinds of signal generators have the character that undertakes to receiver semi-automatic test needs, can use at a variety of general application circumstances of 100kHz~4000MHz frequency limits.

Reliability is high, use simple
According to the strict quality standard of HP company, these a few kinds of signal generators provide stable and consistent performance. The complete electron of HP8647A and HP8648A changes attenuator to handle extent very easily 10 thousand times about a hundred to change, and output n height repeats. Facilitate use face plate interface can shorten the familiar process of handlers improves work efficiency. With the face plate that functional piece means configures accelerated test program build and simplify operation.

The ideal instrument of manufacturing industry and semi-automatic test
HP 8647A and 8648 series are to if cordless telephone, pager and two-way radio correspond,make big batch product the ideal instrument of the stage. HP8647A is the basic model that provides important performance. HP8648 series is mixed except modulation of the high power that can choose, pulse besides undee modulation, have in precision of frequency limits, odd frequency modulation, n and phasic noise respect improve. HP8648 series has precision of ±1dB absolutely scope till 2.5GHz. All all sorts of model offerred the dc frequency modulation that exceeds stability, on the frequency under 100 MHz carrier frequency precision is ±500Hz and small radio frequency leak.
A certain number of application move concordant to adjust like receiver the user interface with simple benefit from benefit from. These a few kinds of signal generators learn easily and use, need seasoned operation staff no longer thereby. Because have register of 300 complete memory and 10 series that can define by the user, reason signal generator gets used to any test processes very easily. Once store the setting,arrive inside register, the face plate before operation personnel can pass or remote control clavier (HP83300A) is opposite quickly its process designing. In addition, HP83301A memory interface still is offerred convey register information from a HP8647/48 the method to another.
Use an occasion to automatic test, HP8647/48 offerred complete GPIB process designing and yard of use SCPI process designing. In addition, HP8648 series is piled up through offerring completely as compatible as HP8656B and HP8657A/B signal generator GPIB and reduced software to develop cost.

The pager with efficient economy checks new method
The only station that couplet used HP 8648A and options 1EP to offer a kind of economy for pager test solution. Options 1EP can add the pager encode function that is used at PDCSAG, FLEX and FLEX-TD to make type for HP8648A. When undertaking the pager checks, HP8648A and options 1EP couplet are used can give out admirable frequency precision, frequency slants precision and function of dc frequency modulation.
