For EVM measurements of signals having symbol rates between 100 kHz and 1MHz. The SM200A/B
will contribute a somewhat higher EVM error for symbol rates outside of this range.

Streaming I/Q and burst I/Q are bandwidth limited to the speed of the available Ethernet connection.

DANL, Residual Responses, Spurious Mixer Responses, and Phase Noise specifications are production
tested and guaranteed only at 23°C (±5°C). Typical performance of these characteristics, over the
instrument’s operating temperature range, will be published as graphs in the User’s Manual.

The SM200 length is 10.97” (0.77” longer) when counting the front panel type-N RF input connector and
0.375” higher when counting feet.
8 SM435 Preliminary Specifications
The following specifications are based on a set of operating conditions, which are the power-up
default settings, unless otherwise stated: 1) Operating in the Preset condition, 2) Using internal
timebase, 3) Video processing set for average and power, 4) VBW, sweep, gain, and attenuation
in the default auto mode, 5) Optional preselectors bypassed. 6) Ambient room temperature (18 -
28C)
IP2 and IP3 testing is performed at a -10 dBm reference level with preselector on, and normalized
to a 0 dBm reference level, which is the functional equivalent of 0 dB RF gain, or the “preamplifier
off” setting of a typical receiver. At maximum sensitivity (-20 dBm reference level), IP2 and IP3
will typically be 20 dB lower.
DANL is tested at maximum sensitivity (-20 dBm reference level)
Frequency Range 100 kHz to 43.5 GHz
RF Input Impedance 50Ω Nominal
(2.4mm connector)
RF Input VSWR <1.5 50 MHz to 18 GHz
<1.6 18 to 24 GHz
<2.0 24 to 43.5 GHz

Calibrated Streaming I/Q 5 kHz to 40 MHz of selectable I/Q bandwidth.
Resolution Bandwidths (RBW) 0.1 Hz (≤200kHz span) to 3MHz (any span) using the
40MHz IBW
30kHz to 10MHz using the 160MHz IBW
Timebase Accuracy GPS disciplined OCXO remains within ±5 x 10-10 when
locked to GPS;
Holdover of ±5 x 10-9 per day for aging
(±2 x 10-8 first day typical)
