ASOPS system with fR=1 GHz repetition rate permits higher scan rates because at a given signal detection bandwidth B and a desired time-delay resolution Dt, the scan rate DfR is limited according to DfR=Dt?B?fR. Thus, at B=100 MHz and a desired Dt of 100 fs, a scan rate of DfR=10 kHz can be realized with fR=1 GHz, while an fR=100 MHz system would be limited to DfR=1 kHz.

The speed rating of many scopes is the repetitive mode limit. However the single shot limit can be much lower, such as 10 MHz. This prevents the acquisition of signals faster 2.5 MHz. Your evaluation of digital oscilloscopes must incorporate each instrument's analog bandwidth, digital bandwidth, and single shot limit, in addition to its repetitive mode limit.

The practical limitations to the time-delay resolution Dt in an ASOPS system are the signal detection bandwidth B and timing jitter between the two femtosecond lasers (look here for more details). Let's assume that a time-delay resolution of approximately 100 fs is aimed at using a signal detection bandwidth B=100 MHz. To achieve this, a 1 GHz system must be operated at DfR=10 kHz, while a 100 MHz system must be operated at DfR=1 kHz (look here for explanation). See similar questions...

This is also called K band. AO-40 operates on K Band with 1 watt into a 23 dBi linear horn antenna. There is 50 kHz of bandwidth and AO-40's 400 baud BPSK telemetry is also transmitted within the K Band transponder. The Beacon frequency is 24,048.035 MHz. The transponder is 24,048.010 - 24,048.060 MHz. AO-40 only transmits on K Band - there is no uplink on this band. See similar questions...

Even the standard K3 comes with a TCXO, so you'll always have one. The external reference option, when plugged in, will work with the TCXO. Note that the external reference module is not completed and may not be available at time of first shipments. But it'll be easy to install yourself once it arrives. Pricing hasn't been set. With the IF DSP in the K3, the issues that are of concern in a fully analog radio are less important. See similar questions...

Unlike most DSP-based radios, the K3 converts from the main IF (8.215 MHz) to the 15 kHz DSP IF without an intervening 455 kHz IF. This helps give the K3 a cleaner sound and better dynamic range since there are fewer conversions. However, this also means the IF crystal filter must have exceptional skirt selectivity to prevent the 15 kHz "image" from getting through. In FM mode, capture effect helps suppress the effect of "image" leakage. See similar questions...

A frequency is used to transmit a signal or data like video. 2.4GHz is the specific wireless frequency that our tranmitters use to send video signal to a receiver. All of our wireless cameras operate on the 2.4 GHz frequency. Range varies from 200ft. to 700ft. depending on environmental conditions. These units are FCC approved. See similar questions...

Currently, most systems use either IEEE 802.11 or 802.11b operating between 2.4 and 2.4835 GHz. As these frequencies become more congested, the U-NII Band 3 at 5.725 - 5.825 GHz (IEEE 802.11a) will be used more. 5.8 GHz also offers data transmission rates greater than 11 MB/s. However, more antenna gain will be necessary at 5.8 GHz for the same distance on 2.4 GHz. 5. See similar questions...

There are three ranges of sound with respect to what humans can or cannot hear: infrasonic, audible, and ultrasonic. Sounds below 20 Hz are infrasonic and cannot be heard by the human ear. Sources of infrasound include severe weather, volcanoes, and seismic activity. Humans can hear sounds between 20 Hz and 20,000 Hz (20 kHz). Once a mechanical defect can be heard at this audible level, damage to the component and possibly to the surrounding components has already occurred. See similar questions...

Do not waste your money on these EPIRBs. Although you may be able to buy one for less than a quater of the price of a 406 MHz EPIRB, these EPIRBs are a left-over from an earlier system that relied on alerting via overflying aircraft. It was only with the advent of satellite detection that they started to become effective. However, in most parts of the world, SAR forces will not respond immediately to 121.5 MHz 'hits', as the vast majority are false alerts. See similar questions...

of February 2009, the International COSPAS/SARSAT System will cease satellite monitoring of 121.5/243 MHz Emergency Locator Transmitter (ELT) beacons. and 243 ELTs have been the standard for many years so many of the ELTs are still in operation in many aircraft around the world. Digital 406 MHz ELT beacons have many advantages over analog 121.5/243 MHz beacons. See similar questions...

The data sheet lists 2.2W with heavy traffic at all ports running 66 MHz. At all ports running 33 MHz and the same conditions power consumption is around 1 watt. See similar questions...

A 66 MHz bus normally drops to 33 MHz when the M66EN signal is driven low. So, you could bring down the primary bus to 33 MHz by tying or pulling low the P_M66EN signal, if that is your wish. More importantly, some other card might do this to you if it is designed for 33 MHz but plugged into a normally 66 MHz bus. The M66EN signals are used directly to the control logic. We do not use the M66EN for strapping, (and thus the M66EN signals are "live" at all times). See similar questions...

ADB) On some processor architectures it is very difficult to find out the clock speed of the processor, and since the kernel does not depend on determining the MHz rating of a processor to operate correctly, MHz simply do not get calculated at boot time. OTOH, BogoMips get calculated because the kernel bases itself on BogoMips data to implement small time delays (busy loops) needed by various drivers in different circumstances.
