# Rohde & Schwarz SMA100A Signal Generator (Pre-Owned)

## Key Features At A Glance

-   Frequency range of 9 kHz to 3 GHz or 6 GHz depending on the installed RF path option
-   Very low SSB phase noise of typ. –134 dBc at 20 kHz offset (f = 1 GHz, 1 Hz measurement bandwidth)
-   High output power up to +18 dBm with overrange up to +28 dBm
-   Electronic attenuator with built-in overvoltage protection across the entire frequency range
-   Pulse modulator with >100 dB on/off ratio (meas., f < 5.5 GHz) and typ. < 7 ns rise/fall time
-   Frequency and level setting times of < 1.5 ms / 1 ms, and < 450 µs in List mode
-   Remote control via GPIB (IEEE 488.2), Ethernet/LAN, USB 2.0, and serial RS-232-C
-   Integrated standard pulse generator in a compact two-height-unit chassis

The Rohde & Schwarz R&S SMA100A is an RF signal generator covering 9 kHz up to 3 GHz or 6 GHz, depending on the installed RF path option. It combines excellent signal quality, high output power, and a comprehensive analog modulation suite — amplitude, frequency/phase, and pulse modulation — in a compact two-height-unit chassis with a color display and an intuitive user interface that graphically shows the signal flow as a block diagram.

The instrument is positioned for production use, where very short frequency and level setting times — under 1.5 ms and 1 ms respectively, and under 450 µs in List mode — along with Fast Hopping support, keep test throughput high. For aerospace and defense work it offers a pulse modulator, an integrated pulse generator, and optional avionics modulation including VOR, ILS, marker beacon, ADF, and DME. As an all-purpose instrument it provides frequency, level, and LF sweeps together with phase-continuous frequency setting.

ValueTronics stocks this instrument in our own 20,000 sq ft secure warehouse at 1675 Cambridge Drive in Elgin, Illinois. Every pre-owned unit is inspected and functionally verified in-house before it ships, while new units ship factory-sealed exactly as received from the manufacturer.

## Accessories Supplied

-   Power cable
-   Quick Start Guide
-   CD-ROM (with operating and service manual)

## Product Core & Specifications

> **Important:** Maximum permissible reverse RF power at the RF output (f > 1 MHz): 50 W from 1 MHz to 3 GHz and 10 W from 3 GHz to 6 GHz with the R&S SMA-B103/-B106 option, and 0.05 W with the R&S SMA-B103L/-B106L option.
