In production and ATE applications, the test equipment
must provide short setting times in order to ensure high
throughput and low measurement costs.
The R&S®SMA100A features the very short level and fre-
quency setting times that Rohde & Schwarz signal gen-
erators are known for and is thus an ideal choice in time-
critical measurement systems. Frequency/level setting
times are already shorter than 2 ms/1.5 ms in normal oper-
ation. A further significant reduction (< 450 µs) is achieved
in the List mode, which uses frequency and level settings
previously stored in a list.
In the Fast Hopping mode, the R&S®SMA100A features
setting times as short as in the List mode. In contrast to
the List mode, up to 10 000 frequency and level pairs can
be addressed as desired via a serial bus.
The electronic attenuator enables rapid and wear-free
level setting of the generator. The level setting range
is –145 dBm to +13 dBm (+20 dBm overrange) for
f ≤ 3 GHz, and –145 dBm to +9 dBm (+16 dBm over-
range) for f > 3 GHz. Higher output levels of +24 dBm to
+28 dBm over the entire frequency range can be provided
by using the relay-switched high-power bypass imple-
mented in the R&S®SMA100A. Overvoltage protection is
integrated as standard over the entire frequency range.
For applications requiring a level setting range not exceed-
ing 30 dB, a more favorably priced solution is available
in the form of a frequency option without an attenuator
(R&S®SMA-B103L/R&S®SMA-B106L).
The high level accuracy and repeatability of the
R&S®SMA100A help ensure results of utmost precision in
series measurements.
With a compact size of only two height units, the signal
generator takes up minimum space in 19" racks.
