OPTIONS
Internal frequency standard: 20 MHz ambIent temperaturE; crystal.
Optional 5 MHz reference crystal oven available (Option 002).
Phase locking: the 3320A/B may be phase locked with a 200 mV to
2 V rms signal that is any subharmonic of 20 MHz from 1 MHz
through 10 MHz (e.g., 1 MHz, 2 MHz, 2.5 MHz, 5 MHz.
10 MHz). BNC female connector.
Rear panel output: front or rear panel output is available. Can be
easily changed
by routing internal cable to front or rear female
BNC connectors. No degradation of performance for rear panel
output.
Auxiliary outputs
Tracking output: 20 MHz to 33 MHz offset signal. Tracks main
output with 20 MHz offset. Rear panel female BNG,
> 100 mV rms/50 n.

> 220 mV rms/50 n (> 0 dBm/50 nl.
Low level output: same frequency as main output but remains
between 50 mV rms and 158 mV rms (into 50 n) depending
on main output level setting. May be used as counter output if
wanted. Rear panel female BNG. sine wave.

Allows bit~rallel word-serial digital remote control of all
functions. (..!) A 33208 with this option will recognize an address
and then accept instructions in aserial fashion. Instructions are in a
7-bit parallel ASCII code. Due to the addressing feature. up to ten
3320B's (with this option) may be programmed from one program-
mer. The HP 3260A Marked Card Programmer may be used as a
programmer for this option.
This option requires 8digital input lines for full control.(!) seven
of the eight are programming input lines and one is a data command
line.
State
Requirements
Full digital isolation is standard with this option.
Timing: max of 5J,l5 per word required to input program data.
Logic level requirements: (same as parallel BCD remote). Switching
and settling times for frequency and amplitude are the same as with
the parallel BCD remote option. For field installation, order
accessory kit HP 11239B.
overrange digit, and avernier control that provides two
digits
of resolution. Arange control provides five ranges of
1000 Hz, 10 kHz, 100kHz, 1000 kHz, and 10 MHz. The
output frequencies are derived from aprecision single
frequency source by an indirect synthesis technique.
1-8. In the 3320A, the
output amplitude is selected by a
0-13 dBm continuous potentiometer. Maximum output
voltage is IVrms into 50 fl. The 3320B has arange of
+26.99 dBm to -{)9.99 dBm with aresolution of 0.01 dB.
The output amplitude can be selected in steps
of 0.0IdB,
0.1 dB, 1.0 dB, or 10 dB. Maximwn
output voltage of the
3320B
is 5Vrms into 50 fl.
1-9. OPTIONS.
Adds two lower frequency ranges, 100.0 Hz and 10.00 Hz, yielding
greater resolution for low frequency outputs (see resolution section
of specifications). These two ranges are fully programmable if digital
remote options are installed.
