3、B. . . . Source Locking Microwave Frequency Counters The Ideal Research Counters This family of Phase Matrix/EIP microwave frequency counters provides fully automatic source locking of virtually any electronically tunable source to the same accuracy and long term stability as the timebase oscillator

4、 in the counter. The ability of the 575B and the 578B to accurately set and stabilize the frequency of a source generator often eliminates the need for an expensive, synthesized signal generator. The 575B measures CW, FM and AM frequencies from 10 Hz to 20 GHz, and the 578B extends that range up to

5、26.5 GHz. With simultaneous power measurement capability, and options for a high stability time base, these high performance counters are ideally suited for applications in: Production Line testing R only Phase Matrix counters feature a YIG-preselected microwave input, which provides unparralled bur

6、nout protection, FM tolerance and frequency selectivity. The YIG preselector works like a tunable bandpass filter, preventing harmonics and other out-of-band spurious signals from interfering with measurement of the desired signal. It also protects the counter from accidental application of high lev

7、el signals (up to 200 watts peak), reducing downtime and the associated high cost of repairing damaged microwave circuitry. Selective Frequency and Power Measurements With a single connection, the 575B and 578B can simultaneously measure and display the input signals frequency and power level in the

8、 microwave band, eliminating the need for a seperate microwave power meter. Within the 25MHz bandwidth of the YIG-preselector, only the selected signals frequency and power level are measured. Signals to be analyzed are selected by keystroke entry of an individual center frequency, or search a range

9、 between a low and high frquency limit. This signal selectivity, combined with 20MHz of FM tolerance at all rates up to 10MHz, allows the 575B and the 578B to make accurate frequency and power level measurements even while the input signal is carrying traffic. Frequency Extension to 110 GHz Option 0

10、6 provides the ability to extend the frequency range of your 578B, in bands, up to 110 GHz. Remote sensors allow you to reach out to connect to virtually any wave guide system without the complications of the additional plumbing necessary to bring the signal to your counter. A wide selection of sens

11、ors provides measurement capability in the wave guide band that you are working in now, and the flexibility to change as your application changes without having to purchase another counter. Only Phase Matrix counters offer the unique YIG-preselected heterodyne technique. Page 2 YIG Filter RF Input 9

The Ultimate Reasearch Instrument Automatic Broad-Band Tuning Operation of the source and counter combination is straightforward and automatic. Lock frequency is easily entered via the front

14、 panel keyboard or via standard GPIB interface. The counter automatically takes it from there, locking the source at the entered frequency. Frequency Storage and Recall For repetitive production testing, an operator can store up to nine lock frequencies and rapidly recall them as needed. This also r

15、educes typical lock times for steps over 10 MHz to300ms. Frequency Limits Automatic amplitude discrimination enables the 575B/578B counters to automatically select and measure the input signal with the highest level, and ignore all other harmonics and other spurious signals that are present. Frequen

16、cy Limits extend this signal selection capability by allowing you to select upper and lower limits, The counter will measure the frequency and power level of only the highest level signal within these limits - even if there are higher level signals present at the counters input. This gives you the a

17、bility to measure the frequency and power of a low level signal (such as a harmonic) even when a signal of much higher level (the fundamen- tal) is present. Power Measurement The 575B/578B family of microwave counters offers the optional ability to simulta- neously measure both the frequency and pow

18、er level through the same input. This often eliminates the need for a separate microwave power meter. With the 25 MHz bandwidth of the YIG tuned preselector, power measurement is made only of the displayed signal, not of its harmonics or other signals present. Thus you can simultaneously measure and

19、 display both frequency and power of individual signals in a multisignal environment. Easy keystroke entry of power offsets can be used to measure power deviation from a reference, or to compensate for losses in external hook-ups such as cable and attenuator losses.

21、 of your source. First, programming steps can be eliminated by letting the counter directly control the sources frequency over its entire frequency range. Second, only a single command string to the counter is needed to set and lock the source. Third, the signal source does not need to have GPIB cap

22、ability. The counter constantly monitors and corrects the source thereby relieving the controller of the task of checking the fre- quency and issuing correction commands. The ability to rapidly step and lock the signal source also saves test time as shown by these examples: Frequency StepTypical Loc
