The Model 4230A Series is a DSP (digital signal processor) based family of single or dual channel, solid state RF power meters. They are capable of measuring RF power levels from -70 dBm to +44 dBm. The RF frequency range and power level range are sensor dependent. Boonton 51000 series sensors provide measurement capabilities for frequencies from 10 kHz to 100 GHz.
The Models 3320, 3321, 3322 and 3323 Filters illustrated in Figure 1, are variable, electronic Filters with digitally tuned cutoff frequencies". The Models 3320 and 3322 have a cutoff frequency range from 0, 001 Hz to 99. 9 kHz. The Models 3321 and 3323 are tunable over the range from 0, 01 Hz to 99. 9 kHz. The pass-band gain is unity (Odb) or 10 (20db), with attenuation rates of 24db per octave outside the pass-band. Maximum attenuation is greater than 80db and the output hum and n ...
The Hewlett-Packard Model 5252A Prescaler Unit is a plug-in unit which converts the Hewlett-Packard Model 5245L Electronic Counter* into a direct reading counter from DC to 350 Me. Prescaling is accomplished, without tuning, by transistor binary dividers, operating over the frequency range DC to 350 Me. Multiple scaling factors (2, 4, or 8) are provided to shorten scaling time at the lower frequencies. The Model 5252A operates by electronically scaling the input frequency, at the same ...
