SIGNAL INPUT
Number of Channels 1
Input Single-ended or true differential
Input Impedance 1 MΩ, 15 pf
Coupling AC or DC
CMRR 90 dB at 1 kHz (Input Range < -6 dBV)
80 dB at 1 kHz (Input Range <14 dBV)
50 dB at 1 kHz (Input Range ≥ 14 dBV)
Noise 5 nVrms/√Hz at 1 kHz typical, 10 nVrms/√Hz max.

AMPLITUDE
Full Scale Input Range -60 dBV (1.0 mVpk) to +34 dBV (50
Vpk) in 2 dB steps.
Dynamic Range 90 dB typical
Harmonic Distortion No greater than -80 dB from DC to 100
kHz. (Input Range ≤ 0 dBV)
Spurious Input range ≥ -50 dBV:
No greater than -85 dB below full scale below 200 Hz.
No greater than -90 dB below full scale to 100 kHz.
Input Sampling 16 bit A/D at 256 kHz

effects).
Averaging RMS, Vector and Peak Hold.
Linear and exponential averaging up to 64k scans.
TRIGGER INPUT
Modes Continuous, internal, external, or external TTL.
Internal Level: Adjustable to ±100% of input scale.
Positive or Negative slope.
Minimum Trigger Amplitude: 10% of input range.
External Level: ±5V in 40 mV steps. Positive or Negative slope.
Impedance: 10 kΩ
Minimum Trigger Amplitude: 100 mV.
External TTL Requires TTL level to trigger (low<.7V, high>2V).
Post-Trigger Measurement record is delayed by 1 to 65,000
samples (1/512 to 127 time
records) after the trigger.
Delay resolution is 1 sample (1/512 of a record).
Pre-Trigger Measurement record starts up to 51.953 ms prior
to the trigger.
