displayed frequency span range: 0 hz to 40.1 mhz variable with 0.1 hz resolution or 10 hz to 40 mhz in 1, 2, 5
accuracy: -0% + 0.2% of frequency span setting
displayed center, start/stop, and manual frequency range: 0 hz to 40.1 mhz with 0.1 hz resolution
accuracy: 1 x 10-7/ month of frequency
marker
readout accuracy ± 0.2% of frequency span ± resolution bandwidth
counter accuracy ± 0.3% hz ± 1 x 10-7/month of counted frequency for a signal 20 db greater than other signals and noise in the resolution for bandwidth setting
resolution bandwidths
range 3 db bandwidths of 3 hz to 30 khz in a 1, 3, 10 sequence
accuracy ± 20% at the 3 db points
selectivity 60 db/3 db <11.1
amplitude
measurement range 1 m ωinput: -31 nvrms to +7.08 vrms
50/75 ωinput: -137 dbm to +30 dbm
all receiver inputs can be overdriven by up to 12.3 db above the range setting, with some degradation in distortion performance.
displayed range scale: 10 division crt vertical axis with reference level at the top graticule line
calibration: 10, 5, 2 and 1 db/division from the reference level
input range -25 dbm to +30 dbm in 5 db steps
reference level range (relative to input range) -100 db to +10 db
marker amplitude accuracy
midscreen at the reference level use reference level accuracy from +30 dbm to -115 dbm, add amplitude linearity below -115 dbm.
anywhere on screen add reference level accuracy, amplitude linearity and frequency response
dynamic range
spurious responses (image, out of band, and harmonic distortion) 50/75 ω input: <-80 db referred to a single signal equal to or less than input range
1 m ω input: <-80 db except second harmonic distortion <-70 db
intermodulation distortion 50/75 ω input: <-80 db referred to the larger of two signals each 6 db below range except 2nd order im from 10 mhz to 40 mhz <-70 db
1 m ω input: <-70 db
residual responses (no signal at input) <-120 dbm using -25 dbm range
residual phase noise (typical at 40 mhz, -10 dbm input) 5 khz offset: -112 dbc/hz
100 khz offset: -120 dbc/hz
sweep
modes continuous, single or manual
trigger free run, line, or external
time 0.2 s full sweep to 200 s/hz of frequency span (swept time excluding auto calibration cycles)
input
signal inputs 50/75 ω: 26 db return loss, bnc connector
1 m ω: ± 3% shunted by <30 pf, bcn connector
maximum input level 50/75 ω: 13 v peak ac plus dc relay protected against overloads to 42 v peak
1 m ω input: 42 v peak ac plus dc (derate by factor of two for each octave above 5 mhz)
external trigger input negative going ttl level or contact closure required to initiate sweep
external reference input 10 mhz (or subharmonic to 1 mhz), 0 dbm minimum level
output
tracking generator
level 0 dbm to -11 dbm with a single turn knob
frequency accuracy ± 1 hz relative to analyzer tuning
frequency response ± 0.7 db
impedance 50 ω; > 14 db return loss
probe power +15 vdc, -12.6 vdc; 150 ma max.
if 350 khz, -11 dbv to -15 dbv at the reference level
video 10 v at the reference level
frequency reference 10.000 mhz ± 1 x 10 -7/month, +10 dbm into 50 ω
