r&s®sgt100a sgma vector rf source | features & benefits -九游官网下载
fast and compact solution – optimized for automated test environments
smallest standalone vector signal generator withintegrated baseband generator
its space-saving design makes the r&s®sgt100a ideal for use in any test system. the compact r&s®sgt100a is a complete vector signal generator with a frequency range of up to 6 ghz and an integrated high-performance baseband generator. it can generate digital rf signals with an i/q modulation bandwidth of up to 240 mhz in rf and supports all common digital standards.
the large memory depth of up to 1 gsample allows long signal sequences and can also store many different signals to minimize switchover times. the multisegment waveform mode makes it possible to switch over between up to 100 different signals within microseconds. should other additional test signals be required, the standard solid-state drive (ssd) speeds up reloading.
fast frequency and level switchover to optimize production throughput
for automated tests, the time it takes to switch frequencies and levels is a key characteristic, especially when using the frequency and level to calibrate or characterize duts such as amplifiers. in addition to lan and usb, the r&s®sgt100a features a pcie interface for remote control to achieve maximum speed.
high output level to compensate for losses in the test system
though compact in size, the r&s®sgt100a achieves a maximum output level of typ. 22 dbm. such a high level is important in a test syste to compensate for losses that arise in cabling and signal paths

low power consumption for reduced heat dissipation and simplified thermal management within the system
the low 65 w power consumption cuts operating costs and reduces heat dissipation. low heat dissipation simplifies the test system's thermal management and allows a high packing density for the generators.
excellent modulation accuracy for large test margins
signal performance is crucial when it comes to offering the right instrument for production applications. this is where the r&s®sgt100a excels: it achieves an extremely low error vector magnitude (evm) of 0.4 % when testing devices for compliance with ieee 802.11ac (with 160 mhz rf bandwidth and higher-order 256qam modulation). its performance enables larger test margins and achieves higher yields in production.

outstanding frequency response due to integrated baseband generator
the very flat frequency response over a bandwidth of 240 mhz makes the r&s®sgt100a flexible and ideal for a wide range of applications. a deviation of just 0.1 db over the entire range clearly reveals why an internal baseband that is perfectly matched to the rf module is a real plus. other features such as frequency offsets in the baseband, high signal bandwidths and lte carrier aggregation also benefit from this linearity.

low phase noise of typ. –133 dbc at 1 ghz and 20 khz offset (1 hz measurement bandwidth)
the excellent performance of the r&s®sgt100a is due to the low phase noise because phase noise directly influences the accuracy of the constellation points of a digital modulation scheme.

excellent level repeatability and level linearity for outstanding reproducibility of measurements
in production environments, the level to the dut over the entire system is typically calibrated to take out any effects of components between the generator and the dut. consequently, an rf generator's level repeatability is more important than its absolute level accuracy when it comes to ensuring that a one-time calibration of the entire system remains valid for a long time in order to maximize uptime.

optional high-performance oven-controlled crystal oscillator for easy integration into test system
typically, all test instruments in a system are synchronized using a 10 mhz reference. the r&s®sgt100a offers an optional high-performance oven-controlled crystal oscillator to provide a stable and precise 10 mhz reference without taking up additional rack space.
ideal enhancement for the r&s®smw200a in mimo applications with more than two antennas
its solid performance makes the r&s®sgt100a the ideal enhancement for the high-end r&s®smw200a vector signal generator in mimo applications. for higher-order mimo setups (such as 4×4 with lte or 2×8 with td‑lte), it is necessary to feed four or even eight signals into the input ports of a base station.
optional analog i/q outputs enabling full-featured envelope tracking testing capabilities
despite the small size, the r&s®sgt100a offers four smb connectors on the rear of the instrument that provide the differential analog i/q output signals with a bandwidth of up to 120 mhz.
the r&s®sgt100a is the ideal solution for power amplifier tests due to its speed, size and performance. to support the testing of envelope tracking pas, an additional envelope signal synchronous to the rf signal needs to be generated.
with the future-ready r&s®sgt100a, this is an easy task since the required software options can be upgraded later without the need for additional hardware. for full flexibility, two different configurations are offered:
equipped with the r&s®sgt-k540 option, the r&s®sgt100a calculates the envelope signal in realtime. this unique feature offers the advantage of test time reduction since no manual calculation of the envelope waveform is required.
the second possibility, which allows the use of customer envelope waveform files, is to split the arb into two independent digital basebands (requires r&s®sgt-k543). this approach combines two instruments into one. a vector signal generator for the rf signal and an arbitrary waveform generator for the synchronized envelope signal.

low acquisition costs
the total cost of ownership incurred for a product involves many different aspects. beyond the initial costs, the generator's low power consumption of just 65 w also saves money in two ways. first, it reduces the power bills. second, it dissipates less heat, simplifying the test system's thermal management.
simple modular design for easy servicing
the r&s®sgt100a consists of just a few modules, making it easy and inexpensive to repair in the unlikely event that a problem occurs.
the built-in test supports the service process, helping to get the instrument back into operation as fast as possible. the recommended three-year calibration interval ensures that the instrument does its job as long as possible and rarely has to be serviced, which in turn reduces the total cost of ownership.
easily upgradeable at customer premises
the r&s®sgt100a offers an impressively flexible customization concept with just one hardware option (the oven-controlled crystal oscillator). all other options can be easily added at the customer premises using key codes – e.g. from 3 ghz to 6 ghz or to a larger bandwidth1). this saves cost and time and maximizes system uptime.
1) the r&s®sgt100a is calibrated up to 6 ghz at the plant. if the generator is upgraded at a much later point in time, it is recommended to recalibrate it up to 6 ghz.
waveform package as ideal production solution
characterizing duts in production often requires using test signals from a number of different standards. in addition to wireless communications standards such as gsm, 3gpp fdd and lte, today's chipsets also support connectivity systems such as nfc, bluetooth® or wlan.
the waveform package is the ideal solution when it comes to inexpensively providing a signal for each standard and to licensing test signals on the r&s®sgt100a in line with these standards. a waveform package for five signals, for example, can generate one signal each for gsm, edge, 3gpp fdd, hspa and lte to test an amplifier.
many remote control interfaces for easy integration into the test setup
in addition to usb and gigabitlan, the r&s®sgt100a comes with a pcie interface as used in computers for remote control. this maximizes data throughput for remote control commands, speeds up waveform downloads and allows very short setting times for various commands, such as those used to change the level, frequency or digital signal.
r&s®sgma-gui pc software
the r&s®sgma-gui pc software, which comes with the instrument, is used for manual operation. it can simultaneously control up to twelve r&s®sgt100a sources and also provides access to all instrument functions and settings via all interfaces.
